Wildfly upgrade from 20 to latest available

[Watchuta Awkin]

Hi to the awesome community! 

After building the wildfly-migration-tool, I noted the migration paths that were available, e.g.; from 20 to 26, and 26 to 31..

C:\wildfly-server-migration-main\migrations\wildfly26.0\wildfly20.0

which are confirmed by the existence of these pom artifactfid's:

<artifactId>jboss-server-migration-wildfly20.0-to-wildfly26.0</artifactId>

<artifactId>jboss-server-migration-wildfly26.0-to-wildfly31.0</artifactId>

However, even though I have WF20.0.1-Final and wf26.0.0-Final,

(also have WF26.0.1-Final and WF31.0.1-Final) all installed on my C:\ drive, attempts to run the migration tool using the above identified migration paths, fail.

There's no point pasting the 26 to 31 attempt, but it unfortunately fails with the same error.

Is there some documentation I missed? Can someone pls help me migrate my WF to the latest version available?

Please note that I also have the wildfly-camel-patch running on my WF. I however have not seen any newer camel patch releases since the WF20 one I already have on my WF20.. so does that mean I am not supposed to upgrade my WF to newer version, since camel patch is not supporting a newer version?
