migration issues from cloud to data center

[Samar Elsayed]

Hi

I am in the middle of migration projects from cloud jira to data center and the below is the process I did :

create backup from cloud jira then import that backup into an intermediate data center instance >> export the projects from that intermediate instance then import them in the final target which is a data center too.

I used the project configurator 3.5.1 

after doing the import, there were some projects that were imported successfully and some failed.

when I checked the logs, I found some exceptions for the ones that failed to be imported 

can someone help me understand the exceptions below.

--------------------------------------------- unknown reason for certain projects import failure

The import was aborted because there were too many errors.
