On MT 4.35, Community 1.65:
I have a multiple Blog installation and need to Refresh Blog Templates converting Classic Blog to Community Blog. The process removes all my current templates including Widgets and places them in Backup.
I would need to manually move (copy and paste) all my custom templates including widgets back to the Blog (there are many).
Is there a way to convert the Classic Blog to Community Blog minimizing the number of custom templates being moved to Backup?
As an alternative, is there a way to promote these to global? Or at least the widgets to Global?
Thanks for your guidance.

You should be able to convert some of those templates to system templates by changing the "template_blog_id" value from whatever blog id is that to "0" ("0", without the quotes, stands for system level).

Thanks Mihai,
I remember the Convert to Global plugin by Mark Carey and tried it. It has a MT 4.35 compatibility problem: convert to global for widgets does not appear in action_items. Modules and all the convert to blog actions work great. Appears to have been developed for MT 4.1(+?) when 4.1 was still using the Widget Manager plugin.
In trying to debug the plugin, I discovered I could simply modify the template_blog_id in the database as you suggest.
If I knew more about the internals of MT and plugin development, I could probably find the problem with widgets convert to global.
Thanks again,
Merv
You're welcome Merv!
When I need to do that kind of things, usually with Custom Fields, I prefer to do it directly on the mySQL database, than using a plugin just for the sake of not relying on external resources which could be subject to conflicts (not working anymore on a given version of MT).
There is one single thing you should be careful about. Always backup your database before making changes to it :)

Great advice Mihai! I'm off and running to prepare for the conversion to Community Blog.
