Different Schema

Hi Is it possible to use SQL 2000 replication with two databases that
have different schema.
At the momenet I am using scheduled scripts to create export files ,
ftp them and then import them, its complex and I need a better way.
Thanks.
Yes - you could use transactional replication with
(a) Transformable subscriptions (DTS integration)
(b) Indexed Views on the publisher
(c) a custom sync object on the publisher

or if theres poor connectivity , is a) or c) the better solution ?

|||(c) would be less strain on the publisher's transactions and holds more
support going forward to new versions of SQl Server.
However I'm a little confused - in terms of failover it is very strange to
change the schema - normally the apps running on the publisher require the
same tables/fields on the subscriber.
