What major impacts or issues will be there when Migrating Sybase 11.x from HP UX to 12.5 on AIX.
Are there any manuals or sites to browse thru?
Since you are changing platforms, you can't dump your database and load it into the new server.
You have to transfer the data somehow. Method of choice would be BCP.
You must also transfer your database schema. Either you have the appropriate scripts to create the database in the new server or you can use some tool to create these scripts.
Some tools are: Sybase Central, Sybase Power Designer and http://www.midsomer.org/#dbschema.pl
