Offline update from ESXi 7.0.2 to HPE ESXi 7.0 U2

Prerequisites:

• ESXI 7.0 U2
• Putty
• HPE Offline Update Bundle

Firstly, you need a copy of the appropriate ‘offline bundle’ update, below you can see this is the customised one for HPE servers.

Upload the offline bundle into a datastore, (that the host to be upgraded has access to) .

While in here, shut down the guest VMs on this host.

Activate SSH....

If you try to connect with an old Version of Putty, you may receive this type of message.

This can be easily solved by switching to a new version.
After that, it works again.
