In any organisation if they are migrating from 6x to 11x, i think obviously they will upgrade the hardware also.
I never worked in the 11x but i have done the same t0 9.3.1 and below is the sample check list.
1) Install the latest version in the new hardware
2) create all the applications and databases in the new server.
3) Create all the directories that are necessary for the production procedures.
4) stop the old server
5) Take the backup of the all essbase files outlines, rule files, calc scripts and report scripts and leve0 data and batch procdures for all the cubes and move to staging area.
6) stop the new server
7) copy the files to the respective folders.
8) Start the server and start all the applications.
9) collect all the substitution variable information from the old server and redefine in the new server.
10) open all the outline and save.
11) collect all the users, groups and filter information from the old server and redefine in the new server.
12) Do the necessary changes for the batch program and test the batch by keeping the input files in the input directory
13) load level0 data and aggregate.
14) Compare and validate the data at the high level.
15) Identify a users who can quickly verify and give feed back. fix if any issues.
16) Map the source interfce to the new server.
17) Define the shedule jobs in the new server.
18) Monitor the batches carefully up to the point everything is stable.
