Switched migrations naming schema to support 32bit systems
Switched migrations naming schema to work on 32bit systems.
New migration_type is "unmark", and schema for files is:
YYYYMMDDXX, where:
- YYYY is year (2014)
- MM is month (10)
- DD is day of month (31)
- XX is sequential number of migration for particular date (01, 02 etc)
Please see documentation in config for more details.
Migration from older database should work from the scratch, but DB backup before upgrading is recommended.
