Error when importing courses in 2.0.2 version

[andre0ani]

Hello,

I have a Chamilo 1.11.38 installation with courses.
I saw that it was best to perform a clean install to upgrade to version 2.0.2, which I did.
From the old version, I exported my courses using the backup tool.
In the new instance, when I try to import one of the backups, I get this error message:
Restore failed: Cannot assign int to property Chamilo\CourseBundle\Component\CourseCopy\Resources\Document::$size of type string
What should I do to import my old courses?

Best regards,

Patrice

First of all check the size of your module, as the one created into C2 can be lower than the total actual size.
Then I would try step by step...
I would export/import Learning path only at first (C1 export SCORM like only the Learning path, no the whole course).
If this works I'll do a selective export including LP and exercises.
Then I'll try the whole module.
Mainly you may have to rework exercises and certificates.
I hope this help.

Thanks for your help.
I've tried just to import / export the learning path but I've got the same error.

Can you change your .env to set APP_ENV to 'dev', try again (it will be much slower but hang tight) and see if you get more details?
Then switch back to 'prod' otherwise you installation will be very slow.
