[Deploying Sakai] [sakai-nakamura] Call for feedback on Upgrade Bundle technical requirements/design

[John Norman]

OK, I'm going to stop here. I am not challenging the desirability of a data upgrade service and I am certainly not challenging "...we need a process where all changes like this and more serious ones can be captured, documented and migration code written". When I looked at the specification work, I got the impression of a two people for 3 months sort of project and I wasn't sure that would be the biggest priority for that level of investment right now, given the resource available and the other things that need to get done. Thus the call for triage, to do the minimum for now so we can get other things done. I am not qualified to do the specification - that needs to come from the development team. Priority setting from the team leads and project manager.

I'll leave it there.

The way that OAE stores data makes it very easy to introduce seemingly minor changes to the data that result in user facing errors and problems. For example, a very small change to the UI to turn-off permissions on categories in personal profiles never surfaced for our users because it required a tiny data migration. Luckily we caught it in QA. (I'm not grumbling, we went to production before 1.0 so that's life.) Now that we are at 1.0 and a number of institutions are in production, we need a process where all changes like this and more serious ones can be captured, documented and migration code written.

It seems to me that there are some basic things that are needed immediately, but others that are potentially nice to have and apply to scenarios that we don't yet experience. Manual upgrades are a pain, but I am not sure how much return on investment this work would produce compared to other priorities.
