Hi all,
We are upgrading Appian. We see two types of upgrade strategies:
1) Stop and backup the server, install a new Appian server and migrate the appian stuff from the backup. Then start the new upgraded server. Following the update guide.
2) Install a parallel server in order to ensure high availability and maintain both environments for some time. Eventually migrate the data to the upgraded server.
Is option 2) possible / recommended? In order to have 2 running servers per environment we might need to have 2 Appian licenses.
Many thanks

Hi,
If you are upgrading to 18.3 version, there are some major changes in architecture. There is no Application server requirement. You need to check your topology before starting upgrade. Better to discuss with Appian Support for more clarity.
Edited Response : Upgrade of one instance at a time is not supported at this time. Better to have approach to reduce down time.
Thanks
