Describe how to copy data from one GemFire XD cluster to another cluster with different host names

Environment

Resolution

In cluster One the following 3 servers are deployed: A, B and C to /opt/data/gemxd/

Create a backup in /opt/data/backup/. The Backup will be created with the format data-timestamp/hostname as following:

/opt/data/backup/2015-02-23-14-19-46/A
/opt/data/backup/2015-02-23-14-19-46/B
/opt/data/backup/2015-02-23-14-19-46/C

On cluster Two the 3 servers are called D, E and F. Note that you cannot restore to a cluster with less servers than in the cluster of origin.

Copy the directories with hostname on cluster One mapped to hostname on cluster Two: A-D, B-E,C-F.
Run restore.sh which will create /opt/data/gemxd/ on servers with hostname D,E,F and restore the data.
