DotNetNuke Upgrade Paths

I was poking around to find the proper upgrade path for upgrading DotNetNuke. I found this post by Will Strohl:

Which shows the following chart:

From Version	To Version
02.00.04	02.01.02
02.01.02	03.01.01
03.01.01	03.02.02
03.02.02	04.03.07 *
04.03.07	04.04.01
04.04.01	04.06.02
04.06.02	04.09.05
04.09.05	05.04.04 **
05.04.04	05.05.00
05.05.00	05.06.02

Upgrade URL to fire the install:
YOURDOMAIN/install/install.aspx?mode=Install

I was currently working with version 4.9.1 for our client and going from one version to another just seemd like such a pain. Especially since the scripts sometimes fail for no reason and when run again, run fine. So I went from 4.09.01 to 5.06.02 and the script ran but the HTML_Community core module kept failing durring the upgrade, it was the only failure in my logs.

I found the error eventually, and it turns out one of our vendors had added a Full Text Index on the HTML_Text table. Once I removed the FULL TEXT from the table and reran the upgrade, direct from 4.9.1 to 5.6.3, it ran without any errors at all.

While I believe the upgrade path is good advice if you have issues, I would recommend doing a direct upgrade to the latest first, if you get errors then follow the upgrade path, elsewise, save yourself some time and try the latest stable version upgrade first.
