SOLVED migration from Truenas Core: pool.import_on_boot stuck on 80%

[jeti]

Hi Guys,
today I migrated from TRUENAS Core to TRUENAS Scale using the manual update File.
The Migration (Update) worked without errors but now it boots up and I can enter the webinterface.
But CPU Load is fairly high and Task Manager shows

It seems to be stuck on 80% already for 5hours...
The Pool is a single 10TB disk ( I know.. just for testing purposes)
is this normal behavior?
thanks

so turns out another reboot and a little more waiting, solved the stuck issue

I seem to remember something similar around Coral. If I stand correct, it may have been caused by the system reading through the entire snapshot list during import.
