From the downloaded distribution, extract the /database/upgrade folder. This folder includes a number of migration*.sql files which upgrade the FlexDeploy schemas along with Patch Release SQL files. You will need to execute these scripts from the version of FlexDeploy you currently have, up to the latest version. And they must be executed in that order. For example, if you are upgrading from FlexDeploy 3.7.1 to FlexDeploy 4.5.0, you will need to execute migration3.7.1_to_4.0.0.sql, then migration4.0.0_to_4.0.1.sql, then migration4.0.1_to_4.0.2.sql, migration4.0.2_to_4.0.3.sql, and migration4.0.3_to_4.5.0.sql. The migration4.0.2_to_4.0.3.sql file includes all of the 403PatchRelease*.sql files in it. Patch Release SQL files are only necessary if you are on a 4.0.3 Patch Release.
