Symbiosis: Migration assistant
We spend a lot of time helping customers with migrations, or advising that they migrate to avoid a dist-upgrade.
It would be nice if Symbiosis Stretch included a script to migrate all domains from Symbiosis Jessie (and maybe Wheezy). Something based on this migration guide would be useful. https://forum.bytemark.co.uk/t/the-symbiosis-migration-guide/2172
It should do as much of that as possible, and carry suitable health warnings, perhaps.
