Beware: Many devices broken after migration

After migration at least 8 devices, both physical and virtual are either broken or weren’t migrated.
3 Aeonlabs dimmers - are missing from the new app, appear in the old one, partially controlled by Alexa as before. Partially means she can turn them on and off but not set %.
Virtual devices - some not migrated.
4 Phillips hue bloom partially work: two work, two disappeared and not working.
Connected directly without hew bridge - this option seems to be not supported anymore!
called support, useless. but polite.
Anyone has similar issues ?
