Setting Up a Planned Cutover to a Mirror Grid

A cutover is a point in time when you transition from the primary grid to a mirror grid. A planned cutover is when the transition is planned and when the original primary grid does not fail completely.

1. Use the following command to take a new checkpoint:

   tibdg -r http://rs0:8080 -g Primary checkpoint create PlannedCutover1-1-2019

2. Use the following command to verify that the checkpoint has been mirrored to the mirror grid:

   tibdg -r http://rs1:8080 -g DR1 checkpoint list

   This command lists the checkpoint ID, name of the checkpoint, location of the checkpoint, and the timestamp on the console window. You must periodically check the output of the command to determine whether the checkpoint you took has been mirrored.
3. Use the following command to activate the mirror grid as the new primary grid:

   tibdg -r http://rs0:8080 gridset setPrimary Gridset DR1

4. Use the following command to disable the maintenance mode on the old primary grid:

   tibdg -r http://rs0:8080 -g Primary grid mode normal
