How to upgrade from version 3.3?

It looks like it's easy to upgrade from version 4.2.  Are the steps the same or is there another procedure when updating from v3.3?  https://www.bigtreecms.org/developers/d … upgrading/   Could someone point me in the right direction or outline the steps, please?  Are there any compatibility concerns (database or code base?), pitfalls to be aware of when upgrading a web application built for v3.3?  Thanks for the advice.

Re: How to upgrade from version 3.3?

BigTree 3.3 has a significantly different database and API structure from BigTree 4.0+. It's been quite some time since I did a 3.x to 4.x migration but when I did, I used this script to migrate the database:

Basically you setup an empty 4.2 install alongside your existing 3.3 install. I believe you then stick the above script inside your 4.2 install's ajax directory and go to http://localhost/4.2/ajax/bigtree-3-to-4/ and follow the instructions in that script. It'll copy over everything into the 4.2 install. From there you'll likely need to modify templates that throw errors to use 4.x function calls (some 3.x style calls no longer work but at this point I couldn't tell you what those are!).
