# What data migration and system transition strategies matter most for IRCM implementation?

&lt;p&gt;The mistake that tends to bite hardest is treating go-live as the finish line and skipping a real parallel-run period on historical balances and usage data, not just new transactions. Migrated-balance discrepancies usually surface weeks later, once a real billing cycle hits an edge case nobody tested. I&#39;ve noticed this echoed in reviews too: one CBiO reviewer described a long change-request process where even small post-launch customizations came with real cost and delay, reinforcing the point about locking down configuration before cutover rather than fixing it after. Getting the data model and edge cases right before go-live matters more than which platform you pick.&lt;/p&gt;
