### Notes

When you upgrade Site Admin to version 25.2, if you are using the Embedded database option and you want to preserve state such as controllers and service groups, you must perform the following database upgrade steps:

NOTE: You must adjust these commands if you have customized the database location, username and password.

1. In `config.json`, change `datasource.url` from

       "jdbc:h2:mem:site-admin;DB_CLOSE_ON_EXIT=FALSE"

   to

       "jdbc:h2:mem:site-admin-v2;DB_CLOSE_ON_EXIT=FALSE"

2. Obtain and extract the additional release artifact `siteadmin-migrate-h2_25.2.0_COMMON.zip`.

3. Stop Site Admin 25.1.0 and save a backup of the existing database (the `data` directory inside your Site Admin `home` directory).

4. Using Java 17, run the following commands in the directory siteadmin-migrate-h2-25.2.0 which was extracted from the zip, replacing `<HOME>` in each case with your Site Admin home folder:

       java -cp "lib/*:h2-1.4.199.jar" org.flywaydb.commandline.Main -jarDirs=jars -url='jdbc:h2:<HOME>/data/site-admin-db' -locations=flyway/h2,db/migration -user=sa -password= migrate

       java -cp h2-1.4.199.jar org.h2.tools.Script -url 'jdbc:h2:<HOME>/data/site-admin-db' -script site-admin-db.gz -user sa -options compression zip

       java -cp h2-2.2.224.jar org.h2.tools.RunScript -url 'jdbc:h2:<HOME>/data/site-admin-db-v2' -script site-admin-db.gz -options compression zip variable_binary
