Moving public folder to another server

Hi,

Could someone advise me on moving public folders from one exchange 2003 server and another exchange server 2003 within the same domain?

I looked up on Internet and found ways such as “Move All Replicas” or "PFMigrate" tool to use. What is the right way to use?

option 1

1. note down how many of public folder Instances

2. "Move All Replicas" to another server

option 2

1. Use PFMigrate tool. For example 25 items at a time to move

> cscript PFmigrate.wsf /S:old /T:new /n:25 /f:"c:\temp\pfmigrate-add.log" /a

2. once all replicas are on new server, remove the old server's replica

> cscript PFmigrate.wsf /S:old /T:new /n:25 /f:"c:\temp\pfmigrate-del.log"/d

3. Rehome public folder

4. Replicating public folder Hierarchy.

EDB is about 20GB so not sure how long will it take to move over WAN. Could someone advise me the best option method?

Thank you very very much in advance.

Cheers,
