categories empty after migration


I have migrated my emclient database and settings to another computer (win10) with success. 

The categories title are correclty imported. However the emails have lost the category assigned. So basically I see the categories list but no email inside. 

Is it possible to fix this ?

I guess it depends on how you migrated from one to the other. If you want an exact duplicate, backup on the one and then restore on the other.

so far I’ve copied y the full emclient folder on the new computer
