If you are thinking of deploying WAS clusters or migrating cluster there are 5 ways you can do it. Below I will look at the 5 strategies and which one is best for each scenario.
Strategy 1: Side by Side – Create a new cell and populate with scripts or manually. Best results with a comprehensive set of scripts or tools for configuration automation.
Strategy 2: In Place – Copy and replace the cell – Recreates the exact v6.x/v7.0 configuration in v8.0. The deployment manager is migrated to the new cell.
Strategy 3: In Place – Copy and replace the DMgr – Recreates the exact v6.x/v7.0 configuration in v8.0. Add new v8.0 nodes and move incrementally by adding new node to deployment manager and replaying old node.
Strategy 4: In Place – Copy and coexist – Recreates the exact v6.x/v7.0 configuration in v8.0Modify the ports in the new cell and coexist.
Strategy 5: Side by Side – Fine Grained – Create a new cell and incrementally copy existing configuration. Uses an intermediate profile, runtime migration and PBC tools
