Check the interoperability matrix to get the "supported" versions: Product Interoperability Matrix (vmware.com)

That does not mean it won't work with any other version, but you will have to test it for yourself I'm afraid. In my experience, basic connectivity will still work, it's the advanced/new features that might give some errors or not work at all, but if you don't need them, then you can just keep using your older clients.

One thing that can be important is the supported CIPHER suites for encryption.
