(1) are the disk formats be compatible; i.e., will I need to perform a logical table reload, or can I bring IUS up on my existing data spaces, My understanding was that Informix themselves were trying to narrow the gap between ODS 7.x and US by maintaining the same internal architecture - i.e. managing data in same page sizes and formats. Doesn't US have different data types though ?? (i.e. don't you have to have specific blade modules to access the data ??). (2) is there a place on the web where I can research the usual known migration issues. There is an online migration guite in the Informix Technical Pages on their web site. This has all the info you need Sorry I can't be more specific. > >

Of course, YMMV. APW. : managing data in same page sizes and formats. Doesn't US have different data : types though ?? (i.e. don't you have to have specific blade modules to : access the data ??). DataBlades implement new types and SQL expressions. If you have SQL-092 style tupes/expressions, then the F.2K engine simply handles them using the code it inherited from 7.3. When you install or create a DataBlade, then instances of the type you ceate are stored on disk adjacent the ones you have from SQL-92. And the routines are executed as part of the SQL query evaluation.
