here is a query I used for the same situation in SQL 2005:
update msdb.dbo.sysdtspackages90
set packagedata=
CAST(
replace(CAST(CAST(packagedata AS varbinary(MAX)) AS varchar(MAX))
,'OLD_SERVERNAME\INSTANCE,PORT#','NEW_SERVERNAME\INSTANCE')
AS varbinary(MAX))
where name like 'SOME_SUBSET_OF_PACKAGE_NAMES'
I believe that it can be modified to work for SQL 2000
