Restoring SQL 2005 Analysis service database backup on SQL 2000
I think the subject line says it all.
Is there any way to import my cubes, measures from SQL 2005 Analysis
service to SQL 2000 Analysis service database.

I do not think so. If you have a data warehouse, you can create a fresh OLAP
2000 cube. If not, you have problems. What you could do is you could
regenerate a SSAS 2005 project with BI Dev Studio, then generate the DW
schema in a relational database from the project, and finally generate the
OLAP 2000 cube from the DW. You have to export the data from the SSAS UDM to
the DW and then process the OLAP 2000 cube.
maybe I am wrong, but at the moment, I cannot imagine an easier process.

Restoring encrypted databases between different servers
Hello:
I'm working with two sql servers instances, ServerA and ServerB, which run under two different service accounts on different machines. They both have a database, DatabaseA, that has some encrypted fields.
If I take a backup of DatabaseA on ServerA and restore it on ServerB, I need to re-encrypt the Database Master Key (DMK) with the Service Master Key (SMK) as follows:
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'pwd used to encrypt DMK'
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY
However, if I again take a backup on ServerB and then restore it on ServerA, I can use the DMK on ServerA without re-encrypting it with the SMK.
Shouldn't I have to re-encrypt the DMK with the SMK everytime I restore from a backup that was generated from a different server?
Thanks,
Cyndi
After the initial RESTORE and ALTER MASTER KEY … ADD ENCRYPTION BY SERVER MASTER KEY on ServerB, a redundant copy of the DBMK (protected by ServerB SMK) will be stored in the mater DB; and as long as the DBMK is the same, the copies should be synchronized. This redundant copy is there to minimize the DBMK management after the initial setup (via RESTORE).
I hope this information helps. Please let us know if you have any additional questions and/or if you have any additional feedback.
Thanks a lot,
