To migrate XorMon instance (source and target PostgreSQL and TimescaleDB should be same) follow these steps:

Source instance

1. Create backup as postgres user

   su postgres
   pg_dump -Fc -f xormon-backup.dump  -d xormon
   

2. Shutdown the instance under xormon user

   su xormon
   cd ~/xormon-ng/
   ./xormon.sh stop
   

3. copy and transfer configuration file(.env-backup) onto the new vm under xormon user

   cp ~/xormon-ng/server-nest/.env ~/xormon-ng/server-nest/.env-backup
   

Target instance

1. Make sure new XorMon instance has network access to all devices on specific ports.
   Refer to this table.
   
   
2. shutdown the instance under xormon user

   cd ~/xormon-ng/
   ./xormon.sh stop
   

3. Prepare target database under under postgres user

   su postgres
   psql -c "CREATE DATABASE xormon"
   psql -d xormon -c "CREATE EXTENSION IF NOT EXISTS "uuid-ossp";" -c "CREATE EXTENSION timescaledb;" -c "ALTER SYSTEM SET timescaledb.restoring = on;" -c "SELECT pg_reload_conf();"
   

4. Restore database

   pg_restore --dbname=xormon --no-owner --role=postgres xormon-backup.dump
   

5. Cleanup

   psql -c "ALTER SYSTEM RESET timescaledb.restoring;" -c "SELECT pg_reload_conf();"
   

6. move the configuration file into place under xormon user

   mv .env-backup ~/xormon-ng/server-nest/.env
   

7. start up the instance under xormon user

   cd ~/xormon-ng/
   ./xormon.sh start
