On Premise to Cloud Migration: What Nobody Warns You About (Until It’s Too Late)
Published 27 May 2026
So, you’ve made the call. You’re moving. The servers are going. The cloud will soon be your new home.
Whether you’re moving to Microsoft 365®, SharePoint®, Egnyte®, Azure®, AWS® or something else entirely, the decision to kick off an on-prem to cloud migration is a big one and the benefits are real. Lower hardware costs, better scalability, improved collaboration across remote teams and a maintenance burden that shifts off your plate. On paper (or “e-paper”), it’s a win-win all around.
But here’s the thing: IT departments who’ve been through it before will tell you that the migration itself is where things get complicated fast. Not necessarily because of the platforms involved, but because of something far less obvious that tends to blindside even experienced IT professionals.
There’s something far less obvious that tends to blindside even experienced IT professionals.
Let’s talk about what that is … and how to make sure it doesn’t happen to you. (Spoiler: It involves file links, a dash of preventable chaos and one surprisingly elegant solution.)
Why Cloud Migration Projects Often Go Sideways
The planning stages of most on-premises to cloud migration projects are impressively thorough. IT project teams map out network topology, user access permissions, security protocols and cutover schedules. Compatibility testing gets done. Stakeholders get briefed. Everyone nods in the right places. Everyone feels prepared.
The moment arrives and the migration runs … and before you know it, users start blowing up the IT department with service alerts and frantic phone calls.
Data is missing. Spreadsheets open but certain figures don’t load. Documents reference files that suddenly can’t be found. Reports point to locations that no longer exist. Productivity stalls. The helpdesk is bombarded. And the IT team, already running on fumes from the migration itself, has to pivot into triage mode … which is about as fun as it sounds.
What causes this? In many cases, it comes down to broken file links.
Without specialized link-remediation tools, that failure rate climbs to nearly 100%.
When files and folders are moved from one location to another (which is, to be fair, literally the entire point of a file migration), any links inside those files that pointed to their old locations now point to … nothing.
Word™ documents that contain an embedded links to a specific set of Excel spreadsheets? Those links are broken now. PowerPoint® decks that reference images or data from a shared drive? Those images and data seem to have evaporated. Probably the most common (and dangerous) examples are financial and accounts spreadsheets that are linked to one another. After migration, these spreadsheets have cells with missing or inaccurate data.
It’s not a bug or a failure of the cloud platform. It’s just physics: data moved and the links are still pointing to the old addresses where the data no longer lives.
The good news is that (unless there was some other major problem during the migration) the missing data still exists somewhere. So, it can be fixed. But at what cost in person-hours and money?
In our experience, after nearly a quarter of a century in this specific niche, an estimated 60–80% of migrations result in some form of missing data due to broken links. For Excel™ workbooks specifically, without specialized link-remediation tools, that failure rate climbs to nearly 100%.
Given that Excel is where most organizations keep their financial data, forecasting models and operational records, that’s a number worth contemplating for a moment (ideally not in front of your CFO).
The Problem Is Bigger Than It Looks
You might be thinking: How hard can it be to fix a few broken links after the fact? The answer depends on the scale of your environment and it generally scales with a vengeance. In a small office with a few hundred files, manual cleanup is painful but survivable. In an enterprise with tens of thousands of documents, many of which cross-reference each other across multiple folders and file types, the work becomes genuinely enormous. And enterprises that are migrating hundreds of thousands or millions of files without the right tool could be dealing with the fallout from this for years.
Avoid a data migration with an “Oh, no!” outcome.
IT teams can spend hundreds or thousands of hours running search-and-replace apps (or custom scripts), tracking down broken references, and still not fully recover everything. It’s the digital equivalent of trying to untangle Christmas lights in the dark, except the lights are your organization’s financial records.
The downstream effects are also worth considering. Wrong financial data fed into executive reports. Compliance documentation that can’t be verified. Project files that appear complete but are missing critical attachments. These aren’t hypothetical scenarios. They’re the kinds of calls IT managers receive in the days or weeks following most file or content migrations … often at hours that were decidedly not in the project plan.
There’s also the rollback question. When broken links cause enough disruption, organizations sometimes have to roll back the entire migration, assess the damage and try again. That’s not just a technical inconvenience. That’s wasted days or weeks, additional staff hours and a serious knock to confidence in the IT team’s ability to manage the project. Nobody wants to explain a rollback to the executive team. Nobody.
The Modern Approach: Protect Links Before You Move Anything
It’s the digital equivalent of trying to untangle Christmas lights in the dark.
The good news is that this is an entirely preventable problem. The key is addressing file links before the migration starts rather than trying to reassemble them on the other side.
This is exactly what LinkFixer Advanced™ was built to do. It’s the only commercially available software that can pre-protect file links before a data migration happens, so that when files and folders are moved to their new cloud location, every link updates automatically to reflect the new path. Users open their files. Everything works.
Of course, there are lots of other ways data migrations can go wrong. So, no one can promise there will be no urgent calls, no missing data, no late-night emergencies and no dumpster fires an hour after a Monday morning cutover. But with the proper use of LinkFixer Advanced, you can eliminate one of the most common causes of such emergencies.
The way it works is elegant in principle. Before the migration, the “Inoculate” function protects all the links, prepping them so that they can quickly be auto-repaired when they get broken. Then, having completed your migration, the “Cure” function can automatically fix all the previously inoculated broken links, and it does it fast.
Files are reunited with files, like a shadow that stays in step. Result? Uninterrupted data availability.
For teams that have already completed a migration and are now dealing with the aftermath, there’s a disaster recovery mode called Modify Links. It’s designed to repair thousands (or millions) of broken links in bulk, far faster than any manual process or generic search-and-replace tool. Think of it as the defibrillator for your post-migration environment.
Nobody wants to explain a rollback to the executive team. Nobody.
What File Types and Platforms Are Covered?
LinkFixer Advanced supports Microsoft Word, Excel, PowerPoint, Access®, Visio®, OneNote® and Project® files, as well as Adobe Acrobat® PDFs, AutoCAD® and Revit® files, HTML, CSS and more. For most enterprise environments, that covers the vast majority of files where broken links do their worst work.
Broken links? Not today, not on your watch.
On the platform side, supported migration destinations include SharePoint (both cloud and on-premise), Microsoft 365, OneDrive, Azure, AWS, Box®, Dropbox®, Egnyte and general file system reorganizations on existing infrastructure.
If you’re refreshing servers, moving to or between cloud platforms, or reorganizing folders and file paths, and those changes will affect links in your files, LinkFixer Advanced is the right tool to keep those links working.
A Note on Excel Files Specifically
I think it’s worth spending a moment on Excel, because the stakes are higher here than with other file types and the damage can be sneakier.
Excel files are the bedrock where organizations store financial models, budgets, projections and data linked across multiple sheets and workbooks. The inter-file references in complex Excel environments can run deep. When those references break during migration, the damage isn’t always immediately visible, which is actually worse than when it is.
A formula might still look fine at a glance but is no longer pulling data from a path (because the path no longer exists), and is quietly returning errors or zeros instead of real data. The spreadsheet looks fine. The numbers look … fine-ish. And by the time someone notices something is off, decisions may already have been made based on those faulty figures. Financial decisions. The kind that tend to generate uncomfortable follow-up conversations with people who have corner offices.
Protecting Excel links before migration isn’t “optional” if you take data integrity seriously. It’s one of the highest-value line items on your pre-migration checklist and it costs a fraction of what fixing the damage afterward will.
Link-Protection Pointers
For IT managers and migration consultants putting together a project plan, here’s a practical framework for incorporating link protection into the workflow, with no heroic manual effort required.
- Pre-migration file & link scanning: Run a link scan across your source environment to generate a full report of every parent file and the child files it links to. This gives you a baseline and, usefully, exposes any links that are already broken before you even start moving things.
- Pre-migration link fixing (if needed): If the above scan reveals you already have some broken links, you may want to go ahead fix them using the LinkFixer Advanced Modify Links feature. This way, you have all your links (or at least all the important ones) working.
If you’re refreshing servers, moving to or between cloud platforms, or reorganizing folders and file paths, and those changes will affect links in your files, LinkFixer Advanced is the right tool to keep those links working.
- Pre-migration link inoculation: Run the LinkFixer Advanced pre-protection (Inoculate) process, so every link is equipped and ready to survive the move.
- During migration: Use whatever migration tools or methods suit your environment and platform. The link protection is now working in the background, independent of the migration tool itself. You can focus on the migration without worrying about what’s happening to the links along the way.
- Post-migration cure: Run the “Cure” process to update all protected links to their new destination paths. Then run a final broken link report to confirm the environment is clean before end users are cut over. This is also the part where you take a deep breath and enjoy the unusual silence of a helpdesk line that isn’t ringing out of control.
- Ongoing link safety (and sanity): File systems don’t stay static. Users rename things, reorganize folders and move files to locations that make sense only to them in that particular moment. Ongoing link protection is worth thinking about for long-term data integrity … before one well-meaning colleague renames a shared folder and inadvertently breaks hundreds of links at 4:45pm on a Friday.
The Cost of Not Planning for This
Some teams skip dedicated link protection because it feels like an edge case or because the migration timeline is tight and the budget is already stretched. The logic tends to be: “We’ll deal with broken links if they come up.”
The problem is that when they do come up (which they inevitably will), they come up everywhere at once and bring friends.
The cost of reactive cleanup (the staff hours, user downtime, potential rollbacks and compliance exposure) typically dwarfs what proactive protection would have cost. It’s the same reasoning that produces the two kinds of IT professionals: those who back up regularly and … those who wish they had.
There’s also the less quantifiable cost of reputation. IT teams are judged heavily on how migrations go. A smooth cutover with no data loss builds trust and genuine goodwill. A migration that leaves users unable to access critical files has the opposite effect and those impressions have a long shelf-life. People remember the one migration that went wrong far longer than the dozen that went right.
Final Thought: Data Migration Is an Opportunity
An on-premises to cloud migration is one of the more significant infrastructure projects most IT teams will take on. Done well, it genuinely transforms how an organization operates.
Files become accessible from anywhere. Collaboration improves. Infrastructure costs come down. The administrative overhead of maintaining physical servers largely disappears, along with that one server room that always smelled vaguely of the 1990s.
Go ahead. Hang up your cape. There’ll be no link-related emergencies on your watch.
None of that should be undermined by something as preventable as broken file links. With the right preparation and the right tools in place before the move starts, you can deliver a migration that actually lives up to its promise … and walk away from it looking like the professional you are.
No cape required. Though, frankly, you’ve earned one.
