vCenter Upgrade fails at post validation stage in VCF 4.4.0.0
The vCenter upgrade sequence was modified starting 7.0 U3C (build-19234570). The reboot happens after the status changed to UP_TO_DATE. Previously, UP_TO_DATE was returning after the reboot happens.
The issue is resolved in VCF 4.4.1.0.
To workaround the issue, please follow the below steps:
Login to SDDC Manager UI.
Wait for the vCenter upgrade to be available.
Retry the upgrade.
