Upgrade strategy

Certified Lead Developer

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
