[Pulp-list] how do I remove migration plugin and data

[Tanya Tereshchenko]

Hi Adam,

There is a story filed to add an ability to remove a plugin and its data.
Please follow it here https://pulp.plan.io/issues/7822 and feel free to
leave a comment to express your interest or reasons to remove.
We plan to work on it relatively soon, but it was not on a high priority
list for us. There are 2 primary goals covered by this story and both don't
seem extremely urgent:
 - space, there is a lot of pulp2 data in pulp3 database that can be removed
 - compatibility with other plugins, migration plugin won't be compatible
with all new pulp3 releases forever, it would be good to be able to remove
it; at the moment it's compatible with pulpcore 3.7+.

However if you think you are running into some problems because of having
the plugin installed, it becomes important to address it sooner rather than
later.
I tried to reproduce your issue by removing the migrated File or RPM
repository/publication/distribution and all worked for me.
Could you share your steps to reproduce the problem? Here or feel free to
file an issue in redmine https://pulp.plan.io/projects/migration/issues/new
The versions of pulpcore and plugins would be good to know (since I'm
testing on the latest), as well as which resources and how you delete them.
Seeing a specific cli command, API call or your script might be helpful.

Thank you,
Tanya
