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 And they must be executed in that order. For example, if you are upgrading from FlexDeploy 3.7.1 to FlexDeploy 4.0.3, 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, and finally, migration4.0.2_to_4.0.3.sql. The 4migration4.0.2_to_4.0.3 upgrade .sql file includes all of the 403PatchRelease*.sql files in it. Patch Release SQL files are only necessary if you are already on previous 4.0.3 Patch Release.
If you are upgrading from a 4.0.3 releasePatch Release, follow the date based sql SQL files in sequence by Date. If you have already a applied specific Patch Release patch then skip it. You can make determination of which Patch Release files to run by looking at Build Time on About window of your FlexDeploy installation. Contact Flexagon support for details if you are not sure. See example below.
