My school began a migration from a commercial LMS to Moodle 1.9 a couple of years ago. I developed a theme, researched and installed several 3rd party modules and created quite a few courses I'm proud of. But then funding for the migration ran out, and we abandoned the project, sticking with the commercial LMS.
We regained funding this year, after the release of 2.0. I'm in the middle of migrating our 1.9 courses to 2.0, and preparing to create many more. It initially seemed logical to me to use 2.0, since that's clearly where the future lies. However, since the vast majority of blocks and activities aren't compatible with 2.0, and many of those that claim to be, aren't yet foolproof, I'm frustrated by my lack of options and the lower level of support available from the wider Moodle community (the majority of whom seem to still be using 1.9.) The support from the 2.0 experts has been awesome, there are just fewer of those folks, and I can rarely search the forums to find questions similar to mine which have already been answered.
So, my dilemma is: Do I stick it out with 2.0 and wait for the eventual added functionalities from the many fabulous module developers? Or do I return to course writing in 1.9, and delay the upgrade to 2.0 for a year or two, when more modules have caught up?
Does anyone have any advice?
