Thanks George, I thought that the uprev was only supported back 3 revisions? That's why I was starting this effort before Rev 16. is anyone clear on this? Is there a 3 year support rule?

I do understand that the rules have changed from 13.6 to 14.x to 15.x and the way we decided handle that is to just up-rev everything and as we respin our designs we will update the rules. Is this a preferred process?
