## Pre-upgrade Tasks/Data Migration

##### Before You Begin

Users should keep the HADB history files, management agent configuration files, log files and repository, and all the data devices outside the installation path. If not, this should be done prior to the upgrade. To move the management repository and configuration files:

1. Stop all the old management agents and keep the HADB nodes running.

2. On each host, move the repository directory to the new location.

3. On each host, copy the `dbconfig` directory to the new location.

4. On each host, update the `mgt.cfg` file, and set the correct path for `dbconfig` and repository directory.

5. Start the management agents using the updated `mgt.cfg` file.
