also my plan was this.
- upgrade the pac strategy to 10.4 from 9.3.
- debug and make sure everything works.
- stop strategy and optotagpreserve upload
- upgrade firmware to 10.4 from 9.3 ( upload cpu and about 12 remote racks)
- debug again in 10.4 make sure everything is working an stop strategy
- optotagpreserve restore.
how does it look?
