Is it possible to upgrade windows server OS on the same machine where Qlik Sense, QlikView, or Qlik NPrinting are installed?
How will Windows Update and Windows Service packs affect Qlik Products?
Questions often arise when upgrading or applying Windows Service packs or running Windows Update, e.g. "Will applying service packs or patches from Microsoft affect installed Qlik software or clients?"
Typically upgrading Windows or applying patches or installing Window Service packs should not affect any installed Qlik products. As a precaution to prevent unexpected effects, below practices are recommended.
General best practices to prepare for updates include:
- Create a Windows Operating System Restore Point (for patches/updates)
- Create a backup of the Qlik environment. See How to take a backup and restore Qlik Sense, What files to include in Backup for QlikView, or Backing up Qlik Nprinting.
- If using certificates, backup the available certificates.
- Make sure your security, account, and GPO settings won´t be overwritten on windows level after the upgrade. Changes to security and account settings due to the GPO can affect service account permissions.
- If a VM or other virtualization technology is in use, take a snapshot.
If you have general questions regarding compatibility of host operating systems, please review the release notes for your release. If you have questions regarding specific patches, raise this query directly in the relevant Qlik product forums.
