  stderr: could not make way for new symlink: httpdocs/current
  rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1650) [generator=3.1.2]

   

• The document root of subscription is set on a symlink.

Cause

The issue is caused by a bug in Plesk Migrator with ID #PMT-3404. It will be fixed in futures updates.

Resolution

As a workaround:

• Log into Plesk on the destination server;

• Go to Subscriptions > example.com > File manager;

• Remove httpdocs/current folder, it can be taken from the error message;

• Go to Tools & Settings > Migration & Transfer Manager > source_server_IP > for affected subscription click [Re-sync]  ;

• Select  Re-sync website files and click OK;
