I copied all the database files of samba3 as is mentioned in the wiki - The
classicupgrade process
<https://wiki.samba.org/index.php/Samba_Classic_Upgrade_(NT4-style_domain_to_AD)#The_classicupgrade_process>

But if the winbindd_idmap.tdb file is in the folder, the errors occur. See
below:

If I remove/delete the file, the provisioning continues and tells me he did
not find the file: *Can not open database idmap, Ignoring: [Errno 2] No
such file or directory*

Can I still provisioning without the file? There is the possibility of
post-migration issues regarding lack of this file?
