We need to migrate 3.x to 4.x and are wondering if we can run both versions on the same server during the migration process? If not, would we have to source another server to make the migration smooth?

Thanks,

Darren

Hi,

You can install and run them together, but you do have to be careful of conflicting ports and other such conflicts

Additionally, make sure that Wowza Streaming Engine is licensed properly to run two or more simultaneous threads
