DVs 5.5 support ESXi 6.5?

[YT86]

we have built new VCSA 6.5 environment and migrated existing ESXi 5.5 host to new VCSA 6.5.

now i am stuck to getting more info to upgrade ESXi host from 5.5 to 6.5. we don't have any test environment where we can test this. so what is the process to go from 5.5 to 6.5.

my only road block is that if i upgrade ESXi 5.5 to 6.5,  then does it make any problem by rest ESXi host running ESXi 5.5 in same cluster?

does it get any problem with VDs version 5.5 ? we have VDs version 5.5 running and it not allowed me to upgrade to 6.5 with ESXi 5.5.

The best practices is to have all hosts within the cluster running the same version and build number, but no problem to have different ESXi versions during an upgrade.

Your ESXi 6.5 will support the vDS 5.5, since the vDS 5.5 is supported by ESXi 5.5 and later. And after you upgrade all the hosts connected to the vDS, you can upgrade the vDS version.
