PGE owns nearly 2800 MW of generating capacity, 1500 pole-miles of transmission line, and supplies electricity to over 800,000 Oregon customers in a 4,000 sq. mile service territory. As part of their regular server vintage schedule, PGE upgraded from PI Server 3.4.375, operating on 32-bit Windows 2003 Server, to PI System 2010, operating on virtualized 64-bit Windows 2008 R2 Server. This presentation will share how PGE performed the PI System 2010 upgrade in-house, and a discussion of lessons-learned and suggestions for others interested in a DIY upgrade.
