Source Installation Procedures

Backing up the Data Store and License Files

In order to rehome, a database backup of the source installation is needed. If running a hot standby configuration, the hot standby license file needs to be copied as well.

Back up and transfer the data store

1. Open an SSH terminal session to Skylight orchestrator on port 22.

2. Log in as the visionems user.

3. Change to the scripts directory by entering: cd /opt/accedian/skylight/scripts

4. Create a backup of the data store by entering: ./ems_backup_mysql.sh -d
   The backup is created and saved in the /opt/accedian/backups directory.

5. Rename the database backup file to rehoming.tar.gz and transfer it to the new virtual machine (target installation) under the /data/backups directory.

Stopping the Application

It is best to stop the application on the source installation while doing the rehoming procedure. The procedure to stop the application is different for hot standby setups.

If you are operating in a Hot Standby configuration

1. Open an SSH terminal session to the Skylight orchestrator on port 2200.

2. Log in as the visionems user.

3. Stop the Hot Standby process by entering: redundancy control stop

Otherwise

1. Open an SSH terminal session to the Skylight orchestrator on port 2200.

2. Log in as the visionems user.

3. Stop the application by entering: service stop app_server

Transferring the Performance Session Data

To preserve the historical performance session data, it must be transferred over to the target installation by following these steps.

1. Open an SSH terminal session to Skylight orchestrator on port 22.

2. Log in as the visionems user.

3. Initiate the transfer by entering:
   rsync -av /data/sdmm visionems@x.x.x.x:/data/
   where x.x.x.x is the IP address of the target installation.
   If rehoming to a redundant configuration, transfer the files over to the virtual machine that will be used as the preferred site.
