RecoverPoint for Virtual Machines two different domains

Hello All, I have recently deployed RecoverPoint for Virtual Machines in our environment. But now I have the challenge of installing RP4VMs in one of our branches, the challenge is not to deploy it, the challenge is that our branch and the target location have different Domains.

Target domain is "remote.org" and source location is "source.org"

So my question are:

1) Since during the deployment I use a service account with Admin credential in the respective Vcenter, How can I make both credentials to work in different Vcenters with different domains.

2) Should I really care about this?

3) I notice that the source admin credential should be able to be admin in the target Vcenter. How can I make this possible? Should I have the same user/password in both sides trying to fool AD.

Here is statement that I found in document:

https://support.emc.com/docu79470_RecoverPoint-for-Virtual-Machines-5.0-Security-Configuration-Guide.pdf?language=en_US

Vcenter Server Credentials:

The user enters VMware vCenter Servers credentials as part of RecoverPoint for VMs

deployment. The credentials allow RecoverPoint for VMs to manage replication, to

orchestrate operations, and to display VMware vCenter Server data in a RecoverPoint for

VMs context.

Any help will be greatly appreciate it.
