I have a single live unit and have also set up a dev cluster suite. The live unit is on ZCS 5.0.13 and the cluster was set up and a backup was restored initially with ZCS 5.0.13 and now upgraded to 6.0.8.

Before cutover I would like to then restore a last incremental and full backup from the standalone to the cluster but was wondering if there will be any issues doing a zmrestore?
