Update Applicability

This "Day 0" update for Veeam Backup & Replication 12 is strictly intended for servers using the RTM release (build 12.0.0.1402).

If Veeam Backup & Replication 12 GA (build 12.0.0.1420) is installed, this update can be ignored as it is not needed. All resolved issues listed in this article were found between RTM and GA releases and were included in the GA release version.

Requirements

This update is intended for existing installations of Veeam Backup & Replication 12 RTM (build 12.0.0.1402) and will update those installations to Veeam Backup & Replication V12 GA (build 12.0.0.1420).

All new V12 installations must be performed using the Veeam Backup & Replication 12 GA ISO that is available for download from Veeam the website starting from February 14, 2023. Version 12 GA ISO includes an updated setup program that addresses several upgrade-related issues reported by early adopters of the RTM build.
