Yes, definitely. I just used it to upgrade a site like that.
The beta version is on
GitHub now, but unfortunately GitHub no longer lets you upload a transport.zip file for users to download.
You could try putting it all in assets/components/upgrademodx/ and running the built.transport.php file in the _build directory. If it works, it will put the transport file in core/packages and you can "Search Locally for Packages" in Package Manager. I'm not sure that will work.
If not, you'd have to download and install MyComponent and do this:
- Put the files from GitHub in assets/mycomponents/upgrademodx/
[li]Copy the upgrademodx.config.php file in the _build/config directory to the core/components/mycomponents/_build/config directory
- Put 'upgrademodx' in the MyComponent _build/config/currentproject.php file (replacing example)
- Launch MyComponent in MODX and run Bootstrap, ImportObjects, ExportObjects, and Build
- Search locally for packages in Package Manager[
Or you can just wait for the release.
