upgrade from 0.8.8 to 1.2 - obolete plugins

[fantomas]

Hello,

I recently upgraded some servers from 0.8.8h (debian 9) to 1.2.2 (debian 10).

we use plugins like settings and rrdclean, which are built in since 1.0.0 and after upgrade I see errors in "plugins" menu saying "Plugin directory is missing".

Is there a way to remove obsolete plugins from cacti?
Should I remove them before upgrade?

or should I simply drop their records from the cacti database? (how?)

Thank you

RRDclean is in the core of Cacti now. In fact, you can set RRD Autopurge in Cacti now. But that's an old version. Try to get yourself to 1.2.14 if you can. Discuss this with the Debian guys.

I know that rrdclean is in the core of cacti.

I am talking about plugins that stay listed in list of plugins after upgrade, after I uninstall them in cacti and remove their directories.

I can remove the rest of attachments, but not rrdclean and settings, they stay listed there and I don't know how to get rid of them.

I attached image of how it looks:
rrdclean is listed, status says "Plugin Error" and when I hover mouse over is, title says "Plugin directory is missing!"

the old directory exists, and the plugin stays displayed and message appear even when I remove the directory.

the same applies for "settings" plugin.

I should note that plugins autom8, errorimage, discovery are easily uninstallable after upgrade

I just don't know if the configuration won't be lost because of this.

Oh, that's a good point. Can you please open a bug in the GitHub bug tracking tool. We need an un-register deprecated plugins function that is run as a part of the upgrade. For you right now, it's simply an annoyance, or should be.
