Plugins - No Compatible Versions Available

This warning message can be ignored
In OME 4.0 that was released, there are additional memory requirements added to each plugin.
The warning message mentioned in OME 3.10 is talking about that memory requirements
if you are not using any Plugins, you can ignore the warning.
if you have any plugins installed, to remove the warning on the installed plugin, you can increase the memory size of the VM.

All these details are mentioned in the KB article link above
OME 4.0 is based on Suse Linux and OME 3.10.2 is based on CentOS
So to move work load from OME 3.10.2 to 4.0, OME migration is needed. Details about this can be found in OME 4.0 User guide.

Respectfully,

Hello, from the screen capture shared previously by another user, it does not mean that the plugins have now become incompatible, this is because with the release of OME 4.0, the min memory requirement has changed for the plugins. The plugins are still usable despite seeing the banner. 

As the online path points to the latest plugin catalog in the https://dell.to/3G9dHHo path for OME 4.0, it will trigger this banner indicating that the min requirements are not met for the plugins

The explanations are clearly stated in the KB article below which was already shared in the thread
OpenManage Enterprise Console and Plugins window shows 'This plugin does not meet the minimum requirements for installation' message

Based on the comments, it looks to be an expectation issue.

Respectfully,
