Unreliable migration

[AdrianC]

I am trying to migrate from one Plesk 12.5.30 to another same version, it fails with this sample error log:

- Subscription 'mysite.com'
|  | 
|  `- error: Failed to create subscription 'mysite.com' in target panel
|     Migration for that subscription is considered completely failed. No further actions are performed for it.
|     Migration tools tried to perform operation in 2 attempts.

|     Subscription already exists on target server: most probably it was created at the previous attempt,

|     It is recommended to:
|     1) Resolve the original issue that caused subscription creation to fail,
|     delete subscription, and then run migration again.
|     OR
|     2) Ensure that created subscription is fine, or the original issue is minor,
|     then simply run migration for that subscription again.

What is this thing ? I need to migrate 30 websites containing 18 databases, users, passwords, emails, etc.
What am I supposed to do now ?

This migration thing is very unreliable. 30 websites are offline and I am losing money while I am looking at an error log that was not supposed to be my problem.

It looks an issue with nginx and some subscription try to disable nginx on both server and remove any subscriptions from new server and try again.

I was able to move on from there but I cannot tell what fixed it.

I restarted the importing of two subscriptions that already failed but appeared (mostly blank) in my destination server, I started again, replaced them and it completed OK, then the next subscriptions transfer also completed, even deleting the initial problematic ones and importing them again worked OK.

Something else I changed was: I added the main subscription/domain , similar to s1.mysite.com , some domains had DNS records related to this "main" host name/subscription/domain.
