Is it possible to upgrade from WAS 6 directly to WAS 9.1 ? If not, what steps do I need to take?

Hi Damon,

  The answer is no, there is no supported path to migrate from v6.1 to v9. Supported migration path to v9 are from v7 and 8.X

  Learn about the migration process before you migrate WebSphere® Application Server Version 7.0 or later to Version 9.0.

  You need to migrate from v6.1 to v7, v8.X (my recomendation 8.5.5) and then to v9

  Depending on your Cell topology (standalone, Cluster) and number of resources (JDBC, JMS,...) maybe you can do the migration manually, replicating configurations in new v9. I have done in several "small" clients not to v9 (yet) but to v8.5.5 ;-)

  To take in mind I: you need to review all yours applications code!!!
 
  To take in mind II: take a view to "migration help services" :-)
