reading the announcement: [ QUOTE ] Backup files from ASL V5.027 will work on ASL V5.1, backup files from the public BETA will work on the final V5.1 too.

As it is a minor release it seems you first have to upgrade to V5 (example 5.027) and then Up2Date to 5.100 (My interpretation not official statement)
