How to Consolidate Multi vSys System into a Single vSys?

We have a multivsys system with extensive configuration in which we have been asked to consolidate into a single vsys. I have worked in Expedition, uploading two configuration and manually moving things over. I have tried load merging the configuation and only copying the vsys information into a single vsys. All met with varying level of success. There seems to be little to no documentation that I have been able to find.

 

My questions are - Is the possible? And what are the best ways to accomplish merging a multivsys system into a single vsys?

@blwavg,

There is a lot of configuration statements that need to be removed, modified, and the like when moving from a multi-vsys system to a sole vsys system. I would really recommend completely rebuilding the configuration file instead of actually using the Expedition tool to do so. This allows you to ensure that everything gets rebuilt correctly. 

 

This is possible, but it's a lot of work to do as you can't easily merge the statements and have it function correctly.

I want to make sure I understand what you are saying. I can take multiple physical palo altos, merge the configuration. I would need to check the routing, interfaces and policies. And that would work with some hiccups, but is possible and something that is supported by Palo Alto. If I were to take a single PA with a multi vsys setup, I have to recreate everything from scratch?

@blwavg,

You don't have to completely re-create the configuration file; the reason that I would recommend doing so is that it generally takes less time then going back and taking out all of the unnecessary statements and verifying that the entire syntax is correct and the configuration file will actually pass the validatation process.

Okay cool. So there is no real method for merging vsys except for doing it essentially by hand. This is really going to suck.
