    If you talk about WAS v8.0, that version is is no longer supported. Therefore the recommendation is to convert/migrate to WAS 8.5.5.
    The best option is to install the new version (WAS 8.5.5 or v9) into the target environment and then use the WAS migration tools to migrate the configuration over.
    For compatibility reasons and the fact that v8.5.5 and v9 have the same lifecycle, you should go with WAS v8.5.5.

    The required migration steps depend on the installation topology (WAS standalone or WAS ND cell on one or multiple nodes).
    You can find details about the migration options here:
    Migrating and coexisting application servers - IBM Documentation
    If you want to move to a new machine, you can find the steps here:
    Migrating cell configurations to new host machines using the command-line tool - IBM Documentation
    If you want to keep your old installation save during the migration, you can use the clone migration approach, see 
    Migrating cells using the command-line tools - IBM Documentation

    Hope that helps

    The problem with the IBM migration tool is that if you decide to migrate to new version (i.e v9), any deprecated values in V9 will be overridden carried over from v8.5 versions and if you have been using the migration tools with all of the previous versions, you may bring a lot of "junk" over. It's an all or nothing migration. Your best bet is to install new 64bit WAS and use UBC to just "migrate" the app components over

    Hello Roberto,
    I'm afraif that this won't work. You'd need to install a new 64Bit WAS and then migrate the existing profile to the new installation. Afaik there is no way to convert an existing 32Bit installation to 64Bit.

    You can not upgrade/convert a 32 bit installation of WebSphere to be 64 bit. It does require a complete uninstall and reinstall of the product so that the 64 bit binaries/SDK can be installed. Just switchingthe 32 bit SDK with a 64 bit SDK is not supported.

    As a workaround for this task, follow the steps below

    1) Make a complete backup of your current WebSphere installation. In addition run profile_root/bin/backupconfig for each profile to capture just the profile's configuration data. The full backup is in case we need to rollback toour previous installation. http://www-01.ibm.com/support/knowledgecenter/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/rxml_backupconfig.html For safety reasons you may also want to make a backup of your Installation Managers Agent Data directory and IMShared directory.This can also be used if we need to rollback.

    2) Uninstall the current 32 bit WebSphere installation. Once uninstalled successfully, delete the remaining WebSphere directory structure.

    3) Install WebSphere back into the same directory structures as before, this time selecting to install the 64 bit SDK. All paths must match exactly.

    4) Create profiles as you had previously with the 32 bit installation. Meaning if you had a DMGR and a local node, create the DMGR profile using the same cellname and nodename as well as servername.Recreate all other profiles and federate them to the DMGR as you had previously. The same nodenames and servernames must be used as previously defined.These profiles are just place holders, but must be created for data restoration.

    5) Now using the backup that we took in step one for each profile, use the restoreconfig to overlay the current config data with our previous config data. http://www-01.ibm.com/support/knowledgecenter/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/rxml_restoreconfig.html

    6) Once all profiles have been restored successfully, you should be able to start and use your 64 bit installation.

    Robert,

    Would this backup -> delete -> install -> restore strategy work if you are changing WebSphere versions? Say 8.5.5.x to 9.0.5.x?

    I am trying to do an in-place upgrade of 8.5.5.8 to 9.0.5.15 on my local (Windows) workstation but when I try to install 11.6 using IBM Install Mgr (and "use existing package group" option), it is complaining that my WAS 8.5.5.8 is 32-bit and 9.0.5.15 is 64-bit. However, I disagree because the .../bin/serverInfo.bat says that the WAS (and JDK) is 64-bit:

    I would follow your path, but how can I ensure the WAS I install will be 64 bit? I had every expectation mine already was...

    Any advice?

    WAS 9.0.5 only supports 64 bit, so there is no chance that the WAS 9.0.5 installation will be 32 bit.
