Update to a maintenance release

The Maintenance releases incorporate a collection of fixes and minor RFEs. IDM 7.2.1 is the latest maintenance release for IDM 7.2. To upgrade an existing IDM 7.2 deployment, follow these steps:

Download and extract the IDM 7.2.1 binary from the ForgeRock BackStage download site.
Copy any customized configuration files, scripts, or workflow definitions from your existing deployment to the comparable directory in your 7.2.1 deployment.
If you are still running IDM 7.2.0, copy the conf/authentication.json file from your existing deployment to the conf/ directory in your 7.2.1 deployment.
Copy the keystore and truststore from your existing deployment to the 7.2.1 deployment. For example:
```
cp -r /path/to/openidm720/security /path/to/openidm721
```
Configure the IDM 7.2.1 server to point to your existing repository:
- If you are using an external DS repository, verify the accuracy of the conf/repo.ds.json file in your new deployment.
- If you are using a JDBC repository, verify the accuracy of the following files in your new deployment:
  - conf/repo.jdbc.json
  - conf/datasource.jdbc-default.json
  - resolve/boot.properties (particularly the values for openidm.repo.host and openidm.repo.port)
Shut down your existing IDM 7.2 server.
Start your IDM 7.2.1 server.
