LUCS upgrade with low downtime

Goal: To perform a quick LUCS update
Complexity: Medium
Preconditions:

This scenario explains the upgrade procedure with 2 systems up and running. Make sure that one server is active (in this example Server 1 ) and one server is passive (in this example Server 2 ) as redundant system.
LUCS Server and Credentials are known
Admin / DB access rights on all machines are given
Installers for new LUCS version are held ready, copied to both systems

2 running LUCS Systems Upgrade

Step	WHERE	USER ACTION	RESULTS / SYSTEM REACTION
1	Server with LUCS Database	Back up / Export your existing LUCS database and store it on a safe location.	Database backup is created
2	Server 2 (Passive) Services	Stop all LUCS component services and uninstall them. Services can be identified with name "Luware-LUCS-<Component>"	Server 2 LUCS services are stopped.
3	Server 2 (Passive) Check LUCS installation folders	Default: C:\Program Files (x86)\Luware AG Make sure that the folders (e.g. ICH, AM… don’t exist anymore), delete leftovers.	Server 2 old folders are cleared.
4	Server 2 (Passive)	Install the new components without starting them ( Don’t forget audio files)	Server 2 components are installed error free.
5	Server 1 (Active) Services	Stop PS service (Persistence) Warning: From now on no reporting data will be written to DB	Server 1 PS Service is stopped,
6	Server 1 (Active) DB / File System	Using "Database Upgrader" Setup, upgrade the DB to the latest version	Server 1 Database is upgraded to newest version, no errors occured.
7	Server 1 (Active) and Server 2 (Passive)	On Server 1 stop all services: Powershell `stop-service luw` POWERSHELL On Server 2* start all services, preferably at the same time for minimal downtime Powershell `start-service luw*` POWERSHELL Allow for 30 to 45 seconds for this command to finish	Services on Server 1 are stopped Services on Server 2 are started
8	Server 1 (Active) Services & File System	Uninstall all services. Make sure that the folders (e.g. ICH, AM… don’t exist anymore) Make sure that the folders (e.g. ICH, AM… don’t exist anymore), delete leftovers. Default: C:\Program Files (x86)\Luware AG → Also see step 2-3	Services on Server 1 are stopped and completely removed.
9	Server 1 (Active)	Install and the new components ( Don’t forget audio files) Start the all services Powershell `start-service luw*` POWERSHELL → Also see Step 2 to check if Services are running	Services on Server 1 are installed and started.
