- Plesk Multi Server
- Plesk Onyx 17.5 for Linux
Migration of a subscription to Multi Server fails:
PLESK_INFO: Migration failed: Failed to transfer additional Apache/nginx directives.
'NoneType' object has no attribute 'protocol'
This issue is submitted as a bug with ID #PMT-4286 which will be fixed in one of the future Plesk updates.
The error can be safely ignored.
The migration action Transfer additional Apache/nginx directives is not required for Plesk Onyx 17.5 and Plesk Multi Server based on Plesk Onyx 17.5.
Furthermore, this action is covered by another action - Restore hosting settings.
