Summary	0004937: Database upgrade should backup old DB prior to performing upgrade
Description	When the user upgrades DB formats, MM should automatically backup the old DB beforehand in case: a) the user wants to revert to the released version of MM b) there's a problem with the upgrade I think that this is generally good practice, but especially during the beta program.
Tags	No tags attached.

Fixed in build	1193

jiri 2008-11-19 12:49 administrator ~0014975	I'd suggest this schema: When MM detects that DB needs to be upgraded, but only when it's a bigger upgrade, e.g. from MM 3.0 to MM 3.1, copy DB before upgrading to file: MM.DB.Pre31 {where 3.1 means the version we are upgrading to}
