DRS is set to Fully-Automated mode and seems to be migrating virtual machines too frequently. Which action can potentially decrease the amount of automated migrations performed by DRS?

Moving the slider to the right increases aggressiveness, causing DRS to migrate VMs for even small imbalances and making the over-migration problem worse.

The DRS Migration Threshold slider ranges from position 1 (Conservative) on the left to position 5 (Aggressive) on the right. Moving the slider left toward the conservative end raises the imbalance threshold that must be exceeded before DRS will generate or execute a migration recommendation. This directly reduces how often automated migrations occur when the cluster is only moderately imbalanced.

Partially-Automated mode still generates migration recommendations but requires manual approval; it changes the approval workflow, not the underlying frequency at which DRS identifies imbalances.

Enhanced vMotion Compatibility (EVC) ensures CPU compatibility for vMotion across hosts but has no effect on the sensitivity or frequency of DRS load-balancing decisions.
