Trying to get a 1.5.4 install running with my old database.

I get this at the top of the admin panel: Your database appears to need patching to a higher level. See Tools->Server Information to review patch levels.

In server information it says:

Zen Cart 1.5.4

Database Patch Level: 1.5.1

v1.5.1 [2013-07-24 15:12:45] (New Installation)
v1.5.1 [2013-07-24 15:12:45] (New Installation)

How to I patch the database?

Thanks.
