Upgrading to esxi 6 - running in parallel 5.5 different Enterprise versions

[SyzygyDE]

hello together,

we want to upgrade our environment from 5.5 Enterprise to 6.0 Enterprise plus.

Can we run in parallel 5.5 Enterprise with 6.0 Enterprise plus ESXi Hosts,

or

can we add the license keys for enterprise plus 5.5 to the existing hosts without any issues of the configuration and then

upgrade the esxi hosts to 6.0 ?

Thank you

Yes, there is no problem since Enterprise Plus will support all features from Enterprise.

can we add the license keys for enterprise plus 5.5 to the existing hosts without any issues of the configuration and then

upgrade the esxi hosts to 6.0 ?

You can, but there is no need... just continue with the option to upgrade the hosts to version 6.0 and assign the Enterprise Plus license.

so esxi6 5.5. and 6.0 Hosts in one cluster is not a problem ?

There is no problem, but I recommend keep this scenario only during the migration.
