I'm not exactly in your boat. I joined a company recently and playing catch up with older systems.
- ESXi 5.1.0 GA 799733
- Veeam Enterprise 6.5https://www.veeam.com/kb2053
It looks like I have to upgrade twice.
6.5 to 8 and then 8 to 9.
What is not clear to me from the KBM article is:
Can I still use SQL Express or do I need a Full blown SQL server? Will the upgrade update my current DB?Important Note Regarding Performance
Veeam Backup & Replication provides an option during installation to create a local SQL Express instance. This option is often taken and as such older versions of Veeam that are then updated may be running on old SQL Express instances. This can affect performance. It may be advised to upgrade the local SQL instance to the most current supported version after first upgrading Veeam to the latest version and update. All versions of Veeam Backup & Replication after 22.214.171.1247 (Patch 1) support SQL 2014.
