[PMT-2825] PMM Error: Failed to generate migration list file, Cause: 'ada97540-1b3b-1db9074b56b5'

[HoracioS]

When trying to migrate, I received this error:

Error: Failed to generate migration list file
Cause: 'ada97540-1b3b-9c44-36b8-1db9074b56b5'
That is a critical error, migration was stopped.

Maybe is a bug?

Best regards,

Thank you very much, but doesn't help.
Is a new Plesk install, anyway, I proceed as KB indicate and got the same error...
I think is a new bug in PMM 1.11.1

Best regards,
Horacio

Hello! Could you please send me a full version of debug log in a private conversation? Actual error stack trace should be listed few tens of lines above.

 

[Aleksey Filatev]

With help of @HoracioS an issue was investigated. Confirmed bug PMT-2825. Looks like it is quite rare case caused by certain state of source server. It will be fixed in nearest Plesk Migrator update.

Have the same thing here with a brand new install
My source server is able to migrate from to other servers I have , so a temp. workaround is to migrate it from server to server I guess...

In the mean time we wait for the update!

Hello @dzaal!

Could you please send me a debug.log of your migration? I need to check is it the same error (PMT-2825)? If yes, we already have a patch to fix it.
