I am upgrading from 188.8.131.52 to 184.108.40.206 and I am replacing disk storage. Do I need to copy images from the old disk storage unit BEFORE upgrade or can they be copied after upgrade ?
I am worried about the Phase1 and Phase 2 catalog conversion processes.
The reason I ask is that I have about 10TB of data on old disk storage unit and only a 1Gb link to copy through, so that means that the system will be down for over a day which I would like to avoid.
what kind of disk storage is this?

Why you want to copy the image, if you want to move the images to some other disk the best approact is to do duplication. You can create new STU for the new disk storage and backups can go to that and you can run duplicate at the same time from old disk to new disk.
I am replacing server hardware , master server (32 to 64bit) and disk bay to which disk STU points to. So the above scenario's concerning manipulating data withing NBU are not an option.
I need to copy the data to the new hardware. Also old hardware and master server are there for the backout plan. The question pertains to, do I need to copy disk STU data before conversion process, which is part of the 7.6 install, or will it be OK to copy after install of 7.6.
My gut feeling is that it needs to be copied before, but in that case what about images on tape which won't be touched. As I don't see the conversion process playing with images on tape.
Nevertheless you never know. That's why I am asking the question.
I have successfully migrated from 220.127.116.11 (32 bit 2003) to 18.104.22.168 (64 bit 2008 R2) no errors in NBCC.
Finally copied all data to new disk storage via robocopy, a 24H process. Not sure it was required as an absolute must (for catalog conversion process) before upgradng from 22.214.171.124 to 126.96.36.199, could have copied afterwards.
Nevertheless would have had more of a manual cleanup to do for images that had expired in catalog but weren't yet on new disk, but were still on old disk.
Hope this serves for someone else.
