How to use GitScrum for platform migrations?

Manage platform migrations in GitScrum with phase tracking, migration tasks, and documentation in NoteVault. Coordinate cutover, track dependencies, minimize disruption. Migration teams with structured approach reduce migration time by 35% [Source: Platform Migration Research 2024].

Platform migration workflow:

Plan - Define approach

Prepare - Build new platform

Migrate - Move components

Parallel - Run both

Cutover - Switch traffic

Verify - Confirm working

Decommission - Remove old
