Migration as a parallel run, not a leap

With a control layer in front of the stack, a SIEM migration becomes a parallel run plus a routing change: both platforms receive the same feed until the new one is proven, then the cutover is a percentage.

What this actually fixes

A traditional migration is an all-or-nothing project: months of planning, parallel infrastructure, two platforms licensed at once, and the risk of a compliance gap if data stops flowing to the old system before the new one is ready. That is why the median migration runs the better part of a year and why so many stall.

The question is not whether you will migrate someday. It is whether you can do it without disruption, and without paying two platforms for most of a year.

How the parallel run works

  • Fork at the source and write to old and new platforms in parallel from one collection layer, with no duplicate forwarders.
  • Transition source by source at your own pace, retiring old routes only when validation passes.
  • Keep full fidelity in open-format storage throughout, so the compliance archive never has a gap.
  • Cut over by adjusting routing percentages, with rollback available by the same mechanism.

Yale New Haven Health moved 30,000+ endpoints onto Microsoft Sentinel in two weeks on this pattern. The dual-license window collapses from quarters to days, and the next migration is a routing change too.
