individual

Sorry if this is a silly question - I've just started using Drupal last year and this is my first major upgrade.

I've got all my sites in one multi-site setup.

A couple of them are very simple, and basically good to go.

Can I upgrade just one of two of them at a time?

e.g. Could I create a new dir for drupal 7 and copy the sites over into it one at a time? (To eventually migrate all of them as the modules I need become available?)

Portland Community Media, in partnership with Denver Open Media, has created documents explaining the rules of scheduling Producer> Project> Programs. The document includes rules for series programs, scheduled on a quarterly basis, as well as individual programs that get scheduled on a first come, first served basis.

I have also included rules on how PCM schedules filler programs.

The focus of this discussion is:
- to communicate current scheduling rules and guidelines
- to discuss other methods of annual, quarterly or daily scheduling rules used by other media centers
