7.6.3 upgrade to 8.1

Hi folks

Planning to upgrade from 7.6.3 to 8.1

From the install guide:

NMM 2.3 clients NetWorker 8.1 does not support NMM 2.3. Update hosts to NMM 2.4

before you update the NetWorker server and storage nodes.

Can you recover data saved in NMM2.3 in NMM2.4?

Also, any data that saved in 7.6.3 cannot be recovered in 8.1,that need to be aware of, that may require some precautions/workarounds/tweaks etc?
