thank you for your help. Upgrade from 7.6 to 8.2(is it safely?) help to take off this containts.

You can indeed upgrade your host "locally" from XS to XCP-ng. Just read carefully our official doc on this

okay. we'll read that carefully and try to do at the not critical servers. but before start of upgrading procedure we'd like to make sure that migration between xcp-ng(8.2) server is working.
I've tried to migrate VM(from xcp-ng 8.2 to 8.2) and caught another error:

Errors in CAPS means an error from the host.

Check host logs, also check dynamic min memory == dynamic max
