Tidying up membership for GDPR by deleting subscribers and subscriptions

I want to delete old subscribers/subscriptions to tidy up the membership list and for GDPR purposes.

I have 'Subscription Renewal Behavior' set to 'Create New Subscription' (but I'm not sure whether I really need this or what the pros and cons are).

So, I have:

a) subscribers who no longer have an active subscription (ie Expired)
b) subscribers who have a current Active subscription but also may have previous Expired Subscriptions.

1. What's the best or right way to go about deleting the old members without deleting any Active subscribers and their subscriptions?

If I go to the Subscriptions tab, filter for Expired subscriptions and delete all of these (or at least those with an End Date of, say, more than six months old), will that leave all the current Active Subscriptions and will that completely delete the Subscribers if all their subscriptions have Expired?

2. Will that also delete the joomla User account for that subscriber? If that doesn't delete the joomla User, is there a way to delete them automatically?

3. I also use acymailing: will deleting the subscriptions/subscribers also delete them from the acymailing user list?

4. Also, I would certainly back up before doing this just in case, but backing up the complete joomla install seems overkill (and backing up just the #__osmembership_subscribers table  is something I'd prefer not to have to deal with). Have you thought about adding a way from inside Membership Pro to backup and restore the complete list of subscriptions and configuration so that this could be done before major changes are made just in case something goes wrong? That would be a very useful feature!

Anyone able to help me with this? What's the best or right way to remove expired subscribers and subscriptions?

I've been experimenting with a test subscription. Deleting the subscription (and these could be selected to be say, subscriptions that had an end date six months prior), also deletes the subscriber record, which is good, but it doesn't delete the joomla user and it doesn't delete the acymailing user, so these would need to be deleted manually.

For a large number of expired subscriptions, this will be a pain to do.

Is there a way to automatically delete the joomla user and the acymailing user when a Membership Pro subscription is deleted?

Thanks, Tuan.

I think it would be useful to have the option to also delete the joomla user.

I'm not sure about acymailing - it looks like users are not being removed from the mailing list when their subscription expires but I need to do some testing to check this properly.

I have it set up so a user whose membership expires is removed from the acymailing list: does deleting a user also remove them from the acymailing list, or does that have to be done manually?

Sorry, Tuan, I don't understand. Which mailing lists will they be deleted from?

Ah, of course.

I also asked about backing up subscribers, configuration, etc so that everything could all be restored if I messed things up. I said:

Is this something you can consider for the future?
