Hello all !

We started to upgrade BIOS & firmware on all our ESXi hosts last week, with the catalog release from past week (indeed). Unfortunately, the catalog was updated on saturday and we have a lot of servers to update left. We don't want to have mixed releases across the infrastructure and don't want to install the newest release (because of security policies, which forbid us to install latest firmware releases and because we can't reboot the ESXi every week...).

Is that possible to use a former catalog release ? If not, how can we ensure to install the same firmware & BIOS release on the remaining hosts ?

Thank you.
