  • Hello, I tried to run on Windows 2003 but I receive no valid win32 error. It is only for 64 bit?

  • @ Luiso - You should be able to run and install SSMA v 5.3 on Windows 2003 Platform without any issues , since its completely supported. Do let us know what specific error you're observing , will be glad to assist.

  • Thanks for releasing this new version. Love this tooling for migration. Mostly use the Oracle to SQL migration, works perfectly.

  • Hi,

    i have the same issue as Luiso. this is in win2k3r2 sp2.

    I get 'is not a valid win32 application' error.

    Nothing gets logged in event viewer logs.

  • I am having the same problem as Law and Luiso.

  • Hi,

    Please help me.

    I am using SSMA v.5.3 version to migrate oracle schema to sql server and the oracle schema size is just 2 GB and around 2800 tables. But the schema conversion step is taking more than 12 hours. Source is linux OS and target is windows 2012. I am using server side migration . Could some one please help me to resolve the slowness.  Very very slow conversion.



  • Can you please document when and why SSMA 5.3 adds or does not add SSMA_Timestamp columns? I have not been able to find this info on the internet and can't figure out what the pattern is.  

  • Hi!

    Does this still require the "SSMA Components on SQL Server (MySQL to SQL)"? If yes, where do I get them from?

    The documentation just says I ought to have a zip file but noit where to get it.

    Lots of Greetings!


  • Sorry, I was stupid. The download is right there...

  • Any word on the win32 install issue?  I'm also on win server 2003 r2 and am getting the error "...SSMA for Sybase 5.3.0 is not a valid Win32 application."  It gives me a similar error if I try to open the Oracle version.  Help!  I want to leave sybase behind.
