Hi Experts,
Hope you can shed some light on this.
We have a client that wants to upgrade their cluster from SAP BI 4.0 SP5 , consisting of two BI virtual servers to SAP BI 4.1 SP7.
They have a Prod environment consisting of only 2 BI servers (Server A and Server B) with CMS deployed on Server A.
What would be the best method to achieve this upgrade (excluding the "In Place Upgrade" directly on Prod environment) ?
( BTW, Is "in place upgrade" recommended at all under these circumstances? What are the possible CONs to doing this?)
If we exclude "in-place upgrade", basically the plan is to:
1. Replicate/clone/copy (whatever is best practice) environments to 2 virtual machines so to be able to run existing Prod environment in parallel while upgrading replicated environment.
2. Then perform the patch upgrade to the replicated/cloned/copied environment
3. Decommission the old Prod environment
Is the above a feasible and a "best practice" plan ?
We would like to avoid content migration with UMT tool and to minimise re-doing configurations like root folders, configuring user security and the like.
We would also like to be able to run these 2 environments in parallel for a while (during UAT in replicated environment)
I've red some posts on web: some suggesting "cloning" the environments some suggesting using of Promotion Management Application , etc.
So I am very confused as to what is the best option in my scenario and HOW IT IS ACTUALY DONE and in what order.
Questions:
1. What is the best approach to replicating the current Prod environment given our requirements above ? What it THE process for this ?
2. If my CMS is on Server A, how do I "replicate" that one, and how do I "replicate" non-CMS server B to new environment ?
3. Once, "replicated" how do I sever the references to the old environment ? (We want to run this in parallel with originating Prod environment)
4. Once we're happy with "replicated" environment" how to we upgrade patch them and in which order ?
Do I use just use "upgrade patch" installation file to achieve upgrade form BI 4.0 to BI 4.1 in the replicated environment?
Hope my lengthy post is clear enough.
Many thanks for your feedback.
