Hi All,
I have performed this task recently and below is the high level plan.
- Identity the column store tables which are not allocated to any specific Table group.
- Allocate table group to all the column store tables.
- Take a backup of the existing table distribution plan.
- Identify wrong table placements in the new distribution plan and correct them.
- Add a new node as slave node to the HANA appliance / convert the standby node to slave node.
- Run the Table redistribution from SAP HANA studio.
