We're looking to transition from SH Bb to SaaS hopefully during summer this year.
Before doing so we have an opportunity to 'clean' some of the legacy data that's been sitting on the VLE since it was introduced.
I'm interested in retiring and archiving some of this clutter (modules, users, roles, building blocks, organisations and templates) before we move to SaaS so we have a (potentially) leaner system.
The dilemma is how far back should I go to start deleting data? I'm thinking of something like going back 6 years and removing anything before then, but also keeping a backup (and being mindful of GDPR regulations).
Does anyone have any specific data retention policies or general guidelines that they are willing to share? And how do you deal with research data that is on the VLE?
