System error when trying to access migration assistant

Edited

When trying to access /admin/migration.action I get the following error (URLs to my confluence snipped for security):

 

Oops - an error has occurred

 System Error

Hi @Timothy Medeiros 

Thank you for reaching out to Atlassian Community.

I understand you see errors when using the migration assistant plugin.

Looking at the error below, I can confirm that it is caused due to MySQL driver version.

java.lang.ClassCastException: class java.time.LocalDateTime cannot be cast to class java.lang.String (java.time.LocalDateTime and java.lang.String are in module java.base of loader 'bootstrap')

 Please check the below bug which details this issue.

MySQL 8 driver causes class java.time.LocalDateTime cannot be cast to class java.lang.String error

As of now, the only workaround is to downgrade to MySQL 8.0.22 driver.

I hope this helps!

Thanks,

Aamir

Thank you, this did the trick!
