If I had to upgrade from an existing Project Server 2007 to 2010 version, how many days can it take? Assuming the following, is a 1 or 2 day estimate reasonable?

  1. Current Project Server 2007 consists of one server farm with one SQL Server machine and one Project Server machine
  2. No 3rd party web parts installation or customization has been made

Are you talking about just the time to upgrade the software? Or do you also want to talk about the time to be able to upgrade your team's skills so that they can use the new software effectively? – Doug B Jan 18 at 13:37
Hi Ali, welcome to PMSE! As it stands now, it doesn't seem to be a question for a PM to answer. Besides, as @DougB mentioned, it isn't clear if your question is from a infrastructure PoV or a management PoV. As it stands now, I'd say the former is your expectation, which doesn't fit to PMSE format. Check our FAQ and change your question if you believe you can make it fit. Bear in mind that ideally, this question must be useful not only for you, but for other members in this community. – Tiago Cardoso♦ Jan 29 at 13:39

The Project Management Answer

The only reasonable answer here is "it depends." It depends on:

  1. The skills of your team. For example, how many of these upgrades have they done in a production or testing environment?
  2. What your migration plan entails. For example, how long will your backups and disaster-recovery planning and testing take?
  3. Your equipment. For example, the speed of your hard drives, tape backups, and network connections.
  4. Your environment. What organizational processes and procedures are involved in such an upgrade?
  5. Your rollback plan. What is involved in a roll-back for your environment, and how long does your team estimate that will take?

The sensible thing to do is to create a staging environment, test your upgrade and roll-back plans, and then factor in your other organizational considerations as required. Naturally, the time it takes to stage an upgrade in order to accurately estimate the production cut-over needs to be accounted for in your project plan, too.
