Please follow the KB79283 to transfer the machines from one to another EPO server.
As per your query, you can select the EPO 4.5, while registering EPO 5.1 server on EPO 4.5 to get registered.
This will work with selecting EPO 4.5 option too.
Additionally, I hvae took some screenshots for one of my customer, I just sharing it.
Note: Please reply to this post, if you find any difficulty to follow the steps as per the Kb79283.
That workded with no probs, thanks for your help.
I'm trying to do the same with an ePO 4.5 > 5.1 system transfer. In my ePO 4.5 install I only have one 1024-bit key and no 2048-bit key. All the agent are bonded to the 1024-bit key.
I've followed the guide, I get the option to transfer the systems so I've tried one, its dispared from the old ePO but even after wakeups has not become manageable on the new ePO.
We are in the same position as you. We currently have v4.5 (Build 1188) and looking to build a new ePO 5.1 server with a new database. Did you have any problems with migrating and managing older versions of software e.g. VS 8.7, 8.5, McAfee Agent 4.5, DLP 9.1
Did you have to upgrade all clients to newer versions or did the latest extensions support the older versions of the software?
In the end my only option was to force the install of the McAfee Agent from the new ePO server, sinse I have already copied over my polices it started conmmunicating with the new server and all is fine!
We run a simple ship with regards to version of VSE 8.8 on all devices so I couldn't comment on compatability with older version, perhaps this would help?
Looking at KB79283, it advises that
"Both the keys (1024 and 2048) should be imported from the ePO server for successful registration so the Automatic Sitelist Import can save without issue."
The environment details list ePO 4.5, however 4.5 only has 1024 bit keys, so it is impossible to import both to the 5.1 ePO server. Does the above statement mean that we can transfer systems from 4.5 to 5.1, but we need to do a manual Sitelist import? And if so, are there any other further considerations after we have transferred the systems (I assume the agent key updater is involved after the transfer at some point?). Or is it the case that a transfer from 4.5 is not actually supported?
It looks like it is indeed supported as there are comments confirming that it works above!
