Transferring Two Tables Between Servers (was Logic)

I have 2 tables with the following structure:
CREATE TABLE [dbo].[table1] (
[RID] [int] IDENTITY (1, 1) NOT NULL ,
[RText] [varchar] (400) NULL ,
[DateModified] [datetime] NULL
) ON [PRIMARY]

CREATE TABLE [dbo].[Table2] (
[GrpRID] [int] IDENTITY (1, 1) NOT NULL ,
[GrpID] [varchar] (10) NOT NULL ,
[RID] [int] NOT NULL ,
[Status] [bit] NULL ,
[SortOrder] [int] NULL ,
[DateModified] [datetime] NULL
) ON [PRIMARY]
GO
I am transfering 2 table between 2 SQL server based on GrpRID from table2.
Since RID is identity in table1 sometimes it is different text for spesific
Rid in second server. Some how I need to get the match the right text from server1
to server2 and if text doesn't exists create a bew entry in table1 with the update to table2
wich should reflect correct RID.
