Should existing engine connection(s) be recreated after restoring a NPrinting Database from another environment?


Environments

NPrinting November 2018 
NPrinting February 2019

Yes, all the existing engine connections will need to be recreated from NPrinting Engine Manager menu, simply because these connections were not present on the other environment you are restoring from. 
Please note that you won´t need to reinstall the engine on the servers, just re-create the connection on the restored environment. 


Example

Objective
We would like to migrate a source environment to a target environment, by restoring source Database on the target NPrinting server
- Source environment: 1 NPrinting server (including both Repository and 1 Engine).
- Target environment: 1 NPrinting server hosting the repository database, and 2 NPrinting engine servers running 1 engine each.

Lab setup
a) Source environment
NPrinting server hostname :Qlikserver1 
NPrinting engine hostname: Qlikserver1
Engine connection: QlikServer1_Engine connection - engine and NP server running on the same instance

b) Target environment
Nprinting server hostname Hostname: Qlikserver4
Nprinting engines hostname: Qlikserver2 & Qlikserver3

Engine connection:
Qliksrv2_engine1 running on Qlikserver2
Qliksrv3_engine2 running on Qlikserver3

Transfer procedure
c) Restore the database from target to source environment following these instructions
d) Delete the QlikServer1_Engine connection in Nprinting Engine manager (click on the settings button, press delete)
e) Create 2 new connections
Qliksrv2_engine1 running on Qlikserver2
Qliksrv3_engine2 running on Qlikserver3
f) After few seconds the 2 engines previously installed on the target environment are show appearing online.

If engines appear offline, please create a support case with us.
