Planning stages of going fomr V5R2 to V5R3, on a 810 box. Not counting the time for a full system save before starting, does anyone know how long the upgrade should take? We're a hospital and need to keep downtime to a minimal.

Thanks. We'll let you know when a new response is added.

It’s really going to depend on the number of CPUs and the amount of Main Memory you have too. You can imagine it’s not going to be short. I think I remember on a 1 CPU 16 GB Power5 box the upgrade took about 3-4 hours total using Virtual CDs. Once I used virtual CDs I will never load them again and wait.

I would plan for 6 hours but think you will be well under that.

    I agree. The upgrade plus installing CUM & Group PTF's should take 4-6 hours, if all goes well. Using optical images is the only way to go. It is faster and you know ahead of time that the CD's are readable.
