Needed to copy the share from one server to share in another server

Hi ,

Needed to copy the data from one share named as xyz in the server 1 to the another share abc in another server 2.

Share xyz data should be copied to the share abc which has already different data in it .We need to copy all the data from the share xyz to the share abc  without deleting any existing data in the destination share.

I know that /MIR option will replace the destination same as source

Can anybody help us in the Robocopy command & switches for this activity?

Any help is greatly appreciated!

Thanks & Regards S.Swaminathan Live & let others live!!!
