Microsoft .NET Framework 4.8 upgrade/installation prerequisite

Using the Setup Wizard - It is preferable for .NET Framework 4.8 to be installed on the Replicate Server machine before running Setup. If .NET Framework 4.8 is not present on the machine, Setup will prompt you to install it. This may require the machine to be rebooted once the installation completes.
Silent Installation – When recording an Install Shield Silent response file (ISS), the recording must be done on a machine with .NET 4.8 already installed on it as the silent installation process does not include a separate installation of .NET framework 4.8.

Upgrading an installation with multiple data folders

When upgrading a Replicate installation with multiple Data folders, only the default Data folder (<Product_Dir>\Data) will be automatically upgraded. The other Data folders need to be updated manually by running the following command:

repuictl.exe -d <data_folder_path> setup install

Compatibility with related Qlik products

This version of Replicate is compatible with the following related products only:

Enterprise Manager May 2026 and all future Service Releases
Compose November 2023 or later
Compose for Data Lakes April 2020 (6.6)
