rename BA client node

Hi all,

I want to rename a BA client node name with "rename node " command as there is a conflict because currently both BA client and TDPO client on this physical linux server are same.

I want to rename BA client node_name from linux1.test.com to linux1 as below
what happens to already backed up files with old name for this BA client ?
will they be OK and can be restored in future?
Are there anymore steps to follow ?

Thanks in advance!
