Yes — this is a common and significant part of what many CSP partners do beyond pure licensing, since they already have the Azure relationship and billing in place. A migration typically involves assessing your current on-premises environment, planning the target Azure architecture, and executing the move (often in phases to minimize risk and downtime).
This is a more involved engagement than typical licensing/billing support, so it's worth discussing scope and approach directly with a partner who has specific migration experience.
If you're considering a move from on-premises servers to Azure, we can walk through an assessment and migration plan with you.
