[-] Migration from Helm 3 failed if some of the source servers did not exist anymore. (PMT-2315)
[-] Migration from cPanel failed in case of broken "shadow" file for some domain on the source server.(PMT-2432)
[-] Migration of the whole server could not be performed without replacement of existing domains. (PMT-2538)

Hi All,

New version of Plesk Migrator 1.10 has been released!

Many issues were fixed based on feedback from customers.

What's new:

[+] Upgrading the Plesk Migrator component is now blocked if a migration is in progress or if some files in the panel-migrator/backend/ directory are locked.
[-] If a reseller was selected for migration, customers belonging to the administrator were migrated as if they belonged to a reseller. (PMT-2697)
[-] Migration from Plesk on Linux hanged if two or more subscriptions with system user names present on the destination server were being migrated. (PMT-2716)
[-] If the Backup Manager component was not installed on the source Plesk server, some critical objects were not restored after migration. (PMT-2696)

[-] Migration stopped if a subscription included into the migration list was absent from the source server. (PMT-2659)
[-] No error messages were displayed in the Plesk Migrator user interface if there were no available IP addresses on the destination server. (PMT-2596)
[-] In some cases the migration could fail because the pre-migration check calculated the number of available domains on the destination server incorrectly. (PMT-2532)
[-] Content placed in folders excluded from the migration was lost. (PMT-2637)
[-] Migration could not be started if a source panel type was selected incorrectly during the first attempt to start a migration. (PMT-2683)

Please share if you see any other possible improvements to Migrator.

I am glad to announce release of Plesk Migrator extension v.1.12

Changes:

[+] Migration of subscription permissions on Windows was optimized for better performance in case of large amount of directories.

[-] Migration from custom hosting: Plesk Migrator tried to add the "www" prefix to a domain with wildcard in name when this option was not allowed by Plesk. (PMT-2865)
[-] In case database is switched from source to target without actual data transfer (DB assimilation), no any messages about this were included into the info.log file during migration. (PMT-2860)
