Saleshandy is a cold-outreach platform with sequencing, sender warm-up, and bulk prospect tools. Outsolvi is a warm-pipeline tracking tool. Migration usually means one of two things: (1) the team's motion has shifted from cold-blast to AE relationship work and Saleshandy's instrumentation no longer fits, or (2) Outlook reps on the current app can't use Saleshandy's Outlook plugin, which works only with the legacy V2 app, and need a tracker that works inside Outlook.
The migration pattern: Day 0 audit which Saleshandy features are actually workflow-load-bearing, Day 1 install Outsolvi alongside Saleshandy, Day 7 calibration with focus on motion-fit (not just engagement-data comparison), Day 14 sequence-engine decision (keep Saleshandy at lowest tier for sequences or replace with Lemlist/Smartlead/Mailshake), Day 30 final cutover. If cold-blast motion is still load-bearing, you might keep Saleshandy on its cheapest tier alongside Outsolvi for warm-thread tracking.
