    WAS Migration 3.5 to 7.0

    --------------------------------

    Dear All,

    We are planning to migrate WAS3.5 to 7.0 . I know the version we have is too old and is going to be cumbersome doing this. WAS is currently hosted in an AIX server .Can you please suggest the best possible migration path for WAS 3.5 to 7.0. Initially we thought of migrating to 5.0 and then migrate to 7.0. But it seems that we have to go straing to 7.0 as per Client. Has anyone migrated WAS 3.5 to 7.0 ? Can you please provide me some tech docs or urls which explains this in detail ?

    Thanks, Jagadeesh

    Hi,


    WAS v7.0 has been shipped for almost two years and is up to 7.0.0.11.


    There are multiple aspects to migration:


    Applications: In reality there are few APIs in WAS v3.5 so there isn't as much that can go wrong. Basically start over with RAD or some other IDE and reuse your current code as snippets to import manually.


    Infastructure: You can do the multiple steps of migrating from v3.5 to v5.1 and then to v7.0 but I wouldn't recommend it. There are enough differences between v3.5 and v7.0 that you're better off just starting with a fresh v7.0 image and moving forward.


    The best migration link is here: www-01.ibm.com/support/docview.wss?rs=18... Take a look at the section on v4.0 impacts to understand what changes you may have to deal with.


    I know this sounds like a big jump but we had a major Japanese auto manufacturer successfully do this more than a year ago

    If your client still insists on moving directly from 3.5 to 7.0 without taking the time to do it right, ask them why they aren't sharing whatever they are smoking.


     


    Seriously, though, your plan to do a two-stage move is better than their insistence on going lockstep by skipping over so many versions.
