What is the best method to restore a DBTest1 (with one .mdf and one .ldf) into DBTest2 (with one .mdf, multiple .ndf data files and with 4 filegroups associated with specific data files). I do not see how the one .mdf file (in DBTest1) can be separated into the other 4 filegroups (in DBTest2). This does not sounds like it is possible with Backup DBTest1/Restore to DBTEST2 or (Detach/Attach) because the underlying filegroup and file structure is different.What method should be used to get the data and structure from DBTest1 (includes 1100 Tables and 550 GBs of Data) into DBTest2 (with 4 filegroups)? Is the following possible:1) First, in DBTest2, execute a script to create tables/indexes on appropriate filegroups. 2) In DBTest2, use scripts to pull data from DBTest1 into DBTest2, for example INSERT INTO DBTest2.dbo.tables with SELECT FROM DBTest1.dbo.tables OR use SELECT/INTO DBTest2.dbo.tables FROM DBTest1.dbo.tables.Or, is it possible to use the BULK INSERT or BULK COPY Options? Export/Import Wizard?Does the Create Index step needs to be done after the data is loaded into DBTest2?Just looking for some practical guidance, suggestions, and recommendations. Thanks.
