Hi all
We have a large HA installation of Enterprise 10.9.1.
Total of 8 servers: 2 Portal, 2 servers, 2 datastore and 2 image servers.
The system directories are on network drive and all the machines works together.
Most data (maybe all) is in external Enterprise geodatabase and published by reference.
We would like to upgrade to 11.1 with minimum down time.
We are thinking about build a temporary installation of 10.9.1, move all data and let people work on it while we upgrade the original machines.
They will be able to add features to exists layers (because they are by reference) but will not be able to create new items, so the system is limited but not down.
We would like to know if there is a good (and safe) way to do it and how it done in details.
Thanks
