Migrate database back to 4.0b3

Due to unresolved issues with dude 6.x we are forced to move back to 4.0b3. Is there a way to migrate the database back from 6.40 to 4.0b3?

I know i can export the dude database from terminal with dude export-db command, however I do not know what file type this is and it appears it is not what 4.0b3 is looking for (.tgz or .xml)

Hello, apiel1!

Probably we may ask Mikrotik team to add posibbility to export Dude v6 db into format which may be used on old Dude versions import.
In your case motivation is: Link bitrate stats not working [SOLVED].

Thank you for sharing your experience!

According to Mikrotik support, there is no way to migrate the database back to 4.0b3. Will have to recreate dude maps and devices manually.
