hi, have migrated from derby to mysql and all data seems to be retrievable and all is working ok...
1/. the existing mangodb folder... is that redundant? can it be deleted?
2/. when i go in system settings, its now unaware of database type and database size... is this normal?
3/. for scada jobs with 500 tags with per sample change logging, will mysql really make the system better? is there a point where derby can manage ok, then struggle?
4/. do the database purge facilities work ok whilst using mysql?
5/. will subsequent mango upgrades respect choice of external DB?
