We're in the process of figuring out quite how much work upgrading to Drupal 7 is going to be. The thing that is really worrying me, is that we currently have our main content as Nodes:
Now, these are linked together using join tables (timesheet for person, address for company, etc) using the node ids, obviously.
Anyway, the possibility of exporting all of this information somehow is quite frankly impossible. The only way we can possibly do it is to be able to import Nodes into the new format and preserve the current Node IDs.
Is this possible?
