We have a configuration of three VM lpars running 5.4. We share RACF and DIRMAINT across all three lpars. This is a Linux only environment under VM. We have started the planning of converting to 6.3. In talking with some people from IBM we have determined that we should not try to share DIRMAINT between the 5.4 systems and 6.3 systems. We are thinking about SSI and what it could do for us. We are looking at how do we migrate to 6.3.
One option that came up was a big bang approach. The idea being we create a three system SSI cluster 2nd level and test as much as we can. Even if we didn't do SSI we would still create all three new systems 2nd level so we could test the RACF and DIRMAINT sharing. Then on some weekend during our maintenance window we would bring down the three 5.4 systems and startup the new 6.3 systems 1st level. Do as much testing as we can and if nothing breaks move forward. Has anyone tried to do this type of migration to 6.3? Have our wheels come off the train for even thinking about doing the migration this way? Thanks..
