Exiting VMware is rarely a single technical decision. For most IT leaders, it’s a mix of aging hardware, rising licensing costs, governance requirements, and the need to modernize without disrupting the business.

The greatest challenge in these projects often lies in the planning rather than the actual migration. IT teams need a path forward when environments are complex, timelines are tight, and early assumptions carry long-term consequences.

These lessons come from first-hand work with IT leaders planning and executing VMware exits in real production environments. Across highly regulated enterprises and fast-growing organizations with shrinking but critical on-prem footprints, the same theme kept coming up: the quality of decisions made early matters more than the speed of execution later.

What follows are some of the lessons they shared—what worked, what didn’t, and what they would do differently if they had to plan their VMware exits again.

Lesson #1: Don’t Choose the Destination Before You Understand the Estate

One of the most common challenges IT leaders described came up early, before any technical work had started. Under pressure to move quickly, teams were often encouraged to pick a target platform first and fill in the details later.

As one IT leader put it, “We had a high-level understanding of what we were running, but not how everything actually interacted.”

Upon closer inspection, harsh realities tended to surface. Applications with very different risk profiles were running side by side. Dependencies were broader, or noisier, than expected. Treating an environment as a single unit makes planning harder than it needs to be.

This is where automated discovery changes the game. When teams use platforms like Matilda Cloud to map exact dependencies and segment the estate by criticality, complexity, and modernization potential, the path forward becomes data-driven, not assumption-based.

Lesson #2: Lift-and-Shift Is an Option, Not the Answer

Lift-and-shift comes up in nearly every VMware exit conversation because it’s the easiest path to picture when timelines are tight. But most IT leaders treated lift-and-shift as a starting point, remaining unsure it would serve the organization well over time.

As teams used AI-driven assessments to gain clearer visibility into how systems were actually used, the picture came into better focus. Some workloads were stable and well-suited for a straightforward move, while others required replatforming.

Crucially, this applies to infrastructure beyond just compute. Teams that "lift and shift" their storage strategy—defaulting to basic cloud block storage—often face massive cost overruns. As we’ve noted before, transforming migration ROI requires modeling advanced enterprise storage, like Amazon FSx for NetApp ONTAP, before a single byte moves.

Lift-and-shift shouldn't be the default; it should be one option among several, applied selectively to genuinely improve the environment.

Lesson #3: Alignment Matters More Than the Plan Itself

Several IT leaders pointed to early alignment as the real inflection point in their VMware exits. Not alignment in principle, but alignment in specifics.

Generic assurances that “everything will work out” didn’t build confidence. What mattered was agreeing early on what success actually looked like, which systems could tolerate change, and where modernization was worth the effort.

In practice, alignment was built by working through the assessment findings together. IT teams and delivery partners reviewed the dependency mapping side by side, separating what actually mattered from what didn’t, and agreeing on which systems would move, modernize, or be retired before execution began.

Lesson #4: Speed Comes from Fewer Reversals, Not More Urgency

Speed is always a priority. What we saw is that the fastest VMware exits weren’t the ones that pushed hardest. They were the ones that changed course the least.

When teams entered execution with a clearer understanding of dependencies, sequencing, and tradeoffs, fewer surprises surfaced midstream. That meant fewer pauses, fewer redesigns, and fewer uncomfortable conversations about scope. Timelines held because the initial plan could withstand scrutiny as the work progressed.

Lesson #5: A VMware Exit Is a Reset, Not Just a Move

For many IT leaders, the VMware exit became a chance to reset how the environment was operated, not just where workloads ran.

Moving out of the data center brought clearer visibility into what was actually in the environment, more consistent application of security and governance controls, and operating models that were easier to sustain over time. The exit marked a clean break from accumulated complexity and introduced a more controlled way of operating going forward.

Closing: What IT Leaders Would Tell Their Peers

The details differ from organization to organization, but the underlying lesson holds. The quality of early decisions shapes everything that follows.

Making the right call up front means the work is done once. There is no second attempt, no prolonged cleanup, and no need to revisit decisions a year later.
