When attempting install or upgrade Veeam Backup & Replication you receive the warning:
“<uuid> component state mismatch has been detected. Please contact Veeam technical support team directly.”
This is due to the fact that the server you are install/upgrading Veeam Backup & Replication on was added as a managed server to another instance of Veeam Backup & Replication that has already been upgraded.
Complete the install as usual and apply the same update to all Veeam servers that are interconnected.
