Just bear in mind the kind of enterprise customers that tend to want on prem software _do not_ want to spend a lot of time deploying or maintaining it but the _do_ want you to support the old version that they're running (meaning security updates and probably fixes for major bugs). It's a very different world from your typical CI/CD SaaS product that deploys frequently and only supports the latest version of the software.
The company I'm with supports our releases for two years, most of our products release quarterly, and many of our customers are kind of annoyed because we release too often (in their eyes). We're looking at getting out of supporting the on-prem game, but personally I think it's unlikely because many of our clients are in government and defense.
