Root-to-root replication with 6.1 and higher
It appears that EMC has changed the replication command set. I am attempting to perform a root to root replication to migrate a Gen3 grid to a Gen4S and I am getting hung up.
Below is the command that used to work:
nohup replicate --dstaddr=DST --dstid=root dstpassword=dst-root-password --id=root --ap=src-root-password --fullcopy
Here is what it is looking for now:
admin@avamar:~/>: replicate -h
Parsed flags: -h
Usage: --dstaddr= --dstid= --dstpassword= --dpnname= [ ]
Example:
replicate --dstaddr=dpn27.avamar.com --dstid=root --dstpassword= --dpnname=dpn27 --id=root --ap=
admin@ntccspdr:~/>:
I have attempted to run this command using the source avamar as the dpnname field as that is what I was told by support and it still does not work.
What am I missing?

I have tried it with and without the dpnname flag with no luck. The source is running code version 6.1.2-47 and I am looking at the 6.0 administration guide. I would image that would be the right one.

You are missing "--dpnname=xxxx" flag. Try giving the same.

The dpnname flag is not required for root-to-root replication. Please ensure that you are using the most recent migration document from support.emc.com.

I tried it with the dpnname="src-avamar-name", that did not work. What else would go there?

The dpnname flag is not required for root-to-root replication. In fact, this flag is forbidden during root-to-root.
There is a document on the support site that specifically covers system migration. I would strongly recommend that you follow it step by step:
https://support.emc.com/docu47262_Avamar_5.x_and_6.x_System_Migration_Using_Root-to-Root_Replication_Technical_Note.pdf?…
https://support.emc.com/docu48259_Avamar-7.0-System-Migration-Using-Root-to-Root-Replication-Technical-Note.pdf?language…
What error message do you receive when you try to perform the replication?
Edit: These documents are only accessible to EMC employees and authorized partners

I'd like to ask a related question:
We are moving a client from a 1x2 grid (2 x 2TB nodes) to a new M2400 using root-to-root migration. Client wants to know how long it will take. In terms of GB/hour, what should we reasonably expect?

The source system's I/O performance will likely be the bottleneck unless you're replicating across a WAN link or something. The read speed from a 1x2 2TB node system will be about 60GB/hr (30GB/hr per node). You're likely to lose some performance during maintenance so call it 50GB/hr on average and that should give you a back of the envelope number.
