Can SQL server 2000 publisher work normally with SQL Server 2005 subscriber ?

or is there any resource about it?

SQL 2000 publisher will work OK with SQL 2005 Subscriber as long as the Distributor is SQL Server 2005 for Transactional Replication.

For Merge replication, Publisher and Distributor have to be SQL 2005. However SQL 2000 and SQL 2005 can both act as subscribers.

For further information, please see BOL topic:
Using Multiple Versions of SQL Server in a Replication Topology|||

thanks for your reply.

I notice that that the publisher can be any version as long as it's newer or eque to the publisher version.

if it is a readonly subscriber ,the subscriber can be any version.

BTW,all of the version is newer than sql 7.0 sp4.

Thanks again.
