Before performing anetwork cutover (migration or upgrade), it is essential to collectbaseline datato ensure that services operate normally before and after the change.
Importance of Pre-Cutover Information Collection:
Identifies Network Baseline– Helps comparepre-cutover and post-cutover performance.
Detects Hidden Issues– Ensures that no existing network issues interfere with the cutover process.
Prevents Service Interruptions– Ensures all dependent services are accounted for.
Provides Rollback Plan– If issues arise, administrators canrestore previous configurations.
