    We are in the initial phase of upgrading our current 8.0.3 MSP11 app to 9.0.1 app and would also like to switch our database platform from Oracle to SQL server. We have upgraded to LSF9 about a year ago. Has anyone done an app plus a DB change at the same time? If so what what pitfalls did you encounter. BTW we are running Lawson on Windows NT.

      Hi Eddie, I have done some of those, and am currently working on one that is AIX/DB2 --> Windows/MSSQL. The two biggest things to deal with are 1) data (e.g. erroneously entered dates) that is valid in one database, but doesn't translate to the other database, and 2) all of the other products/applications that the users have bolted-on to the Lawson database, e.g. Crystal Reports/Enterprise, Access databases, etc. The good news for you is that at least you're not changing platforms as well
      Thanks for using the LawsonGuru.com forums!

        Hello, Eddie!

        Application upgrade 803->90x require both source and target databases to be of the same kind to my knowledge. The reason - lawson uses Java code that does direct SQL queries to do most of the data move. So, you can do Oracle-to-SQL conversion either before or after upgrade on the target server. You can use Lawson tools, such as DBCOPY, to do this. They will handle data conversion between databases properly, albeit they will work slow (in comparison to native database tools).

        Thanks.

        Alex.
