Capistrano deployment in load balancer with sticky session


I used to have a couple of applications running on a single server. Now they have been migrated in two server, load balanced using sticky sessions. They told me that files in the first server will be replicated during the night to the secondary. I still have my old Capistrano recipe to be updated. I thought I can create two different environments, one for the first server, one for the second one, something like production1 and production2; what do you think about it? Do you have any suggestion or advice?

Why sticky sessions? I wasn't my choice.
