How this shortlist was made: agencies were chosen for relevant public work, depth in the category and coverage across the project lifecycle, based on public evidence, mainly provider sources. Team quality and comparable client references still need checking before selection. See How We Choose.

How to choose

  • Ask how they assess and prioritize workloads before migrating.
  • Check cloud partner tiers on the vendor's own directory.
  • Clarify cutover, rollback and cost controls.
  • Request references with a similar estate.
