Old images/attachments not working

Hi,

I have gitlab-ce-11.7.5-ce.0.el7.x86_64 on Centos 7. The gitlab-ce was initially installed about 4 years ago and it was upgraded many times since then.

I just found that when trying to access old attachments from old Issues none of them work. I narrowed down the issue to be related to the ID used in the URL of the attachements.

The old style paths were: https://gitlab.domain.com/uploads/example/example/4523793de6/3.png - showing 404 error

The new style: https://gitlab.domain.com/uploads/example/example/72d005b359c4f542dd0c8e786da71846/3.png - working

Is there any way to fix this? Please help.

Thanks in advance.
