Hi Community, good day!
In my article, you will find information about some conditions that may prevent upgrading from version 12.3 to version 13, such as:
- Unsupported OS for the VBR server;
- Unsupported SQL Server version;
- Unsupported .NET version;
- Old components still registered (Cloud Connect, Enterprise Manager, Console, Agent, Plug-ins);
- Legacy license type, and more.
Here a small table that can be used as a reference to organize the upgrade process in the best possible way; keep in mind that this is just a small example based on a very simplistic scenario.
Build a table like below:
Scenario
- VBR 12.3 on Windows Server 2016
- SQL Server 2016
- VMware ESXi 7.0 U1
- Windows Server 2016 ReFS repository
