Change CLM-WAS to CLM-Tomcat

Hello,
I have a CLM 4.0 version working with WAS 7.0 and I would like to change it to tomcat. It's possible?
What does I need to do? I also want to upgrade the CLM version, so can I make the application server change while I'm upgrading the CLM?
Thanks,
Renato.

This is covered in the product documentation: http://www-01.ibm.com/support/knowledgecenter/SSCP65_5.0.0/com.ibm.jazz.install.doc/topics/t_migrate_tohmcat_was.html the approach is the same for all applications.
While you can upgrade and migrate in one go, I would suggest to do one step at a time and test it worked successfully.

Hi Ralph,
The link shows me how to change from tomcat to was.. but I have installed on was, but because I didn't have an ldap server, managing users is making me it difficult. So I want to change from was to tomcat. It's is possible? Can I just follow the upgrade (from 4.0 to 5.02) guide like i'm using a tomcat and will install it?
Thanks for your help.

If your main concern is user management and you don't use LDAP servers, then you will have a big task ahead transferring the user information from WAS (custom registry or file based federated registry) to Tomcat. I have not found any documents detailing this operation though - probably because you're moving in the opposite direction as most other users.

Hi Donald,
I think there will be manual task migrating the users. My main concern is that I'm moving  the opposite directon that most users take. I think I will need to manually create the users in the tomcat users file. I'll make some tests and let know if it works.
thanks!

My suggestion would be to set up a test system on Tomcat and Derby. Do a repotools -export users on the original system. Then do an import of the users with repotools.

You should be able to use the resulting tomcat-users.xml for the final system.

Once the server is down, backup and replace the tomcat-users, potentially copy/paste any admin users you newly created during the migration back into the new file.
