I currently have Windows 2003 server standard edition not r2. I saw that\ndfs replication under r2 does delta replication and the non r2 version does\nnot. Is there an upgrade path to r2? Or is there an upgrade for the dfs\nreplication service that will enable delta replication? Or would i have to\ngo out and buy a copy of windows server 2003 R2 even though it is a "minor"\nupgrade?
