The Calm Before the Storm

We are officially two weeks away from taking our production instance down and migrating from 11.5.10 to 12.1. You'd think I'd be swamped with problems and issues from every which department, but as of today the only thing I have to work on is documentation (training and validation), and rewriting reports. --Sadly our discoverer reports aren't going to migrate so well since they were built on OPM inventory views.

My mind is going about 2,000 mph trying to see if I've missed any testing or any possible business process that might be affected by the upgrade but so far things look good. I wish I had a little more 'stress free' free time so I could update this blog with things I've learned during the upgrade but I think those entries are going to have to come later.

I will however make a small list of things to consider during your upgrade

• Discoverer reports/workbooks don't migrate, at least that is what Oracle consulting told us. If you are using discoverer before the migration you're going to have to recreate your workbooks after the migration (assuming those workbooks are built on views that get changed during upgrade)
  
• In OPM users are forced to choose an existing lot number when performing move immediates and adjust immediates. In 12.1 users are not forced to choose existing lots. They can enter a new lot any time (subinventory transfers, account alias transactions, inter-org transfers)
  
• This one is random but in 11.5.10 we had routings setup which had resources with a usage of 0. In 12.1 if you have a primary resource assigned to a routing and that primary resource has a usage of 0 then when you run collections, the Recipe which uses that routing will not be collected and it will not show demand for that product/raw materials
  

Those are just a few thoughts, hopefully they might help you out during your upgrade. Well, I have more reports to rewrite, wish me luck.
