Grouping into subprocess

Hm ... I am not sure what your question is ?!?

Create a separate process model and call it using a "sub process" or  a "start process" node. Is that what you are looking for?

Yes, I have this flow which I would like to group into one unique subprocess. I should create a separate process model including all of this tasks?

Yes.

A sub process is nothing else than a normal process model. You can build a modular process that "calls" several other processes. These are then called "sub processes".

My concern is, I have already created a wide process model, and now I want to separate isolated group of process nodes into differentiated subprocesses, as it is a better practice. Let me show you the following example:

I would like to create a separate subprocess for each of the indicated (red and green) group of process nodes.

The difference is the process is already created. My approach is to create a new process model and copy and paste the isolated process nodes into the new process, however I am not sure this is the best way to do it. 

The documentation I have found about this makes reference to creating a subprocess from scratch, rather than creating a subprocess from existing process nodes

Thanks!

I see many "Query Database" nodes. I do not recommend to use them, except of special and rare cases.

There is no "creating a subprocess from existing process nodes" in Appian. You could copy the existing model twice and remove nodes as required.
