Hi,

I am running Rancher with two environment and each contains around 20 stacks. I wanted to move one environment to different Rancher instance due to internal reasons.

So I took export of mysql and imported to standalone mysql server and pointed Rancher to this mysql. It started fine and stopped it for now.

Can I run both the Rancher instances at the same time for 1 or 2 days? what are the impacts? Do i need to run the agents again?

I will keep one environment per Rancher instance and will delete the other one.

Thanks  
Gokul

@garjunan I can only tell you, out of experience, this might not end up well. it might make more sense to spin up another deployment and migrate the workloads.

I’d imagine you have the docker/rancher-compose files handy? You could start transitioning services over to your new deployment using those. Maybe have an outage window to migrate your data… I dont think there is any definitive documentation in this area as it heavily depends on whats deployed.
