Migrate BI from Old server to New Server

[dipti1]

1. We should reuse the existing Qlik Sense license key and transfer it from the old server to the new server.
2. We will perform a fresh installation on the new server using the same Qlik Sense setup file currently used on the old server.
   
   The above points acknowledged by the client now, how to proceed?

Hi @dipti1 

Following this guide will make it very easy
https://community.qlik.com/t5/Support-Updates/Qlik-Sense-Migration-Migrating-your-Entire-Qlik-Sense/...

You'll need to consider a few important things:

1. be sure to install the same version and patch on new server, after that you can start doing the migration. if you do the migration in the proper way, you will not need to apply the license manually.

2. Whether the new server will have a different name, you shoudl carefully follow this part on the shared link

If you don't do this, among other problems, all your connections and data sources will fail because the keys are linked to the certificates of the server you have running.

3. If the new server will have the same name, it's a bit simpler because you can skip the bootstrap and cluster service file paths steps. (you could megrate old certificates)

4. You might also have problems running both servers simultaneously. My suggestion would be that after you have the necessary backups, shut down the old server and start working on the new one. This is not mandatory but can avoid some mess regarding license llocations

5. check if the environment is single node or mulitnode. for each case, the same link has the complete information.

6. check if the new servers IP has access to the existing data sources

hope this helps,
Best,

Hi @dipti1 ,
As acknowledged, we will proceed with the Qlik Sense BI migration by reusing the existing license key and transferring it from the old server to the new server.A fresh installation will be performed on the new server using the same Qlik Sense setup version currently running on the old server.

Next Steps:

Take complete backup from old server
Prepare and validate new server
Install Qlik Sense on new server
Transfer and activate license
Migrate apps, configurations, and schedules
Perform testing and user validation
Plan final cutover and go-live

I hope this will be helpful for you.

In addition to the points already mentioned, one thing that has helped in several migrations is validating all service account permissions before the final cutover.

A few checks that are worth doing early:

• Verify the Qlik Sense service account has the same local/admin permissions on the new server.
• Confirm access to shared folders, QVD locations, database drivers, and UNC paths from the new host.
• Export and validate scheduled tasks before switching production traffic.
• Test reloads manually after migration because some connectors/drivers may behave differently even on the same Qlik version.
• If certificates are regenerated due to hostname changes, it’s also worth rechecking external integrations and APIs that depend on them.

Another recommendation is to keep the rollback option available until users validate reloads, streams, and security rules on the new environment.

The shared migration guide from Rafael is definitely the safest approach for preserving the environment cleanly.

Hi @dipti1 

1. Not sure what all the labels are for??? - many are not relevant to the question so I suggest to clean it up to avoid confusion please and only keep relevant to the topic. For example "Cloud" label is totally misleading! - Thanks

2. always refer to the documentation: https://help.qlik.com/en-US/sense-admin/May2026/Subsystems/DeployAdministerQSE/Content/Sense_DeployA... which allows you to choose the version of software you have and then follow it step by step.

cheers
