The requirements for Guard 2.0 are less than 1.2, as each encrypted item does not take up a database entry.

Storage requirements are essentially just the keys

In order to add the additional database tables and update the lookup table, an upgrade process is required. Instructions here title=AppSuite:OX_Guard#Update_1.2_to_2.0
