I am upsizing an access DB to SQL Server. I'v had trouble running the upsizing wizard, so I imported both the data and schema via DTS. ALl the data and schema imported just fine. The field types were on target for the most part. My biggest concern is the relationships which din't make it as well as primary keys, and so forth. I was able to fix this without much effort. Here is my question: The access DB is running on a production site. I needed to first do the upsize and work out all the SLQ issues and make sure the system will work once the switch is ultimately made. So in an effort to get all the data in (and tell me if I'm wrong here) into SQL Server, I couldnt have any identity fields or relationships in place inthe new SQL server DB inorder to preserve all the referential data. Once the data is in I then changed all the autonumber columns to identity columns. Everything is great. Now, once I can be sure everything is running well, I'll need to get all the data from the production access DB. My plan is to export the SQL server schema and then import the access data into the new DB. Do I need to get rid of all the identity columns (just set to INT) in order to get the data in properly. ALso, do I need to wait until all the data is in the new SQL Server production DB before establishing all the relationships? Any thoughts, or ideas are greatly appreciated! |
