Trouble trying to install Jira Cloud Migration Assistant

[swat09]

Hi, I am trying to install JCMA into my Jira Core Server. I have version 8.5.5 due to which I had manually install it. But when I tried to access it, I only see a blank screen. Has anyone faced the same issue or know how to resolve this?

Hi @swat09 Does the plugin installed successfully on the Jira and it is enabled, if you facing error while installing the plugin then you may try to clear the plugin cache as per the steps mentioned in the below document and then try again installing the plugin

If your plugin is installed and enabled check if all the modules of the plugins are enabled or not.

Let me know how it goes.

Thanks

Actually, while installing it, an error showed up even though the app showed up in the list of installed plugins. I'll try clearing the cache though.

Hi @swat09

Please try to install the plugin once again and same time open the catalina.<current_Date>.log  file from you installation logs path, here you can find the error message.

Thanks & Regards

Hi @Balaji Sankar 

Thank you for your reply. This is the error message that I've found in Catalina :
