Im new here, I just need a little guidance/help, I've just inherrited a Symmetric DS setup that is very unstable but is also on a version I think is around 2 years old, we have 6 servers currently in the setup with between 64-90 client nodes connected to each server and they are all stressed out at current. Will Symmetric keep working if I upgrade 1 server and run it with 5 on the old version and 1 on the new version all connected to the same datasource?
I do plan to upgrade all however I need to test it first and it isso unstable Im going to have to start straight in prod without doing any testing prior
I appreciate any help you can offer on this

Andy, what version are you on currently? I assume your 6 servers are in a cluster (since they are pointed at the same datasource). You would need to update those 6 at the same time since they will update the database schema for the newer version. You can update the clients later; the protocol is background compatible.
I recommend updating to 3.9.18 which we have lots of users running on which are very stable.
Also, for stablity, it's imperitive to make sure cluser.locked.enabled=true on all 6 of the servers.

Hey Mark thanks for that, they are not clustered to my knowledge, should we have them clustered? how would I check that? (sorry for the basic questions on that part). We are running version: 3.4.8
