Question

Can you have multiple database connections in the liquibase.properties file?

Answer

No, the liquibase.properties file itself is designed to support only a single target database connection at a time. Liquibase reads the liquibase.properties file to load default settings, including details about the database connection (url, username, password, etc.), but it cannot handle multiple connections directly within one properties file.

The reference database can be set for the diff and diff-changelog commands, but that reference database cannot have scripts deployed to it.

Alternative approach

While you cannot have multiple databases specified in a single liquibase.properties file, you can have multiple different properties files and use the defaults-file parameter to select a specific properties file to use.

For example:

liquibase --defaultsFile=liquibase-db1.properties update

liquibase --defaultsFile=liquibase-db2.properties update
