Exception when attempting to obtain Users From Spaces for migration

When my Confluence migration is failing when attempting to download the list of users from the selected spaces - I get a warning when reviewing the plan, and a previous migration attempt also failed.

The exception obtained from the application log (added below) is stating that it cannot find a class which should be in the standard Spring Core library, which I've confirmed exists, so I can't see any obvious reasons why this isn't working.

I had no simliar problems with a Jira cloud migration.

Does anyone have any ideas?

Thanks,
Brad

Environment Details:

  • Confluence v7.15.0
  • Confluence Cloud Migration Assistant v3.2.6
  • Database: Percona MySQL 5.7

Having same issue with a client's system.

Are you also getting the "We can't communicate with your server" error pop-ups while going through the steps? According to another post, responded to by Atlassian, this seems to do with Apps, but I'm not migrating any of those.

I can connect to the instance just fine on the open net, but their network could still be blocking (some) IPs from AWS-like services.

None of this explains why a core Spring class cannot be found.

Also, the migration refuses to save. I can get all the way to the final screen, but no matter if I select Save or Run Now, I'm returned to am empty migrations screen and have to start over.

Also, getting 500's for static images that can't be found and need to be pulled out of a jar to restore. Maybe this instance had a bad restore, recently...

Honestly, I just wish the CCMA or the logs had ANY information what-so-ever that was in any way even a little bit helpful.

Hey Derek,

Yeah, I was getting the same generic error pop-up - that was when I did some digging and found that exception was logged each time that popup showed. I'm not migrating any apps either.

I'm running my local Confluence in a standard hosting environment (i.e. not AWS or any other cloud env), so I don't think it's network related.

I didn't have a problem saving the migration, nor did I see any issues with the static images, so those could be different issues.

Just to play around, I tried adding the spring-core jar to the migration plugin lib, but it didn't seem to make any difference at all.

Unfortunately, I only want to migrate one space from my current enviroment, which doesn't leave me much choice but to use the CCMA. Very frustrating, especially since the JCMS worked perfectly.

@Brad Kazazes

I think we found out it was related to an out-dated CCMA.

The app will not update automatically - we had to visit the Marketplace, download the latest version for our hosting type, and Upload it manually.

After updating and starting a new migration, the issues went away.

GL!

Thanks @Derek White I had no idea the app versions could be out-dated. I manually upgraded CCMA to 3.3.2 which fixed up the issue.

Cheers!

I had no idea, either. Some, apparently, can be.

Had a similar issue once with JCMA, but during it's communication with the Cloud version it would alert me to being out-dated and prompt me to go and upgrade it. The same, unfortunately, does not seem to occur with the CCMA.

Glad I could help!
