hi,

We are planning to migrate from Websphere Portal to Liferay Portal.

So can anyone please help me on how to go about it? What are major points which need to be considered?

What do you have to migrate? Custom portlets? What features of Websphere are you using?

You need to determine what features of Websphere you currently use - that includes portlets delivered with Websphere, authentication setups etc.

Also, you need to check your custom-developed additions (e.g. portlets) and how much of IBMs proprietary additions to the standard they are using.

And you need to determine what Liferay features you will use to replace your currently used functionality.

Basically: This question is far too broad to be answered in a simple forum post.

Olaf mostly listed all points but to summarize:

1. What functionality needs to be migrated? Are they JSR-168 or JSR-286 compatible?
2. Content migration strategy if you are using IBM Workplace Web Content Management?
3. Users
4. Roles and access rights

Point 1 should be fairly simple if you have strictly followed the portlet specification and haven't used any WPS specific features. Point 2 you can make semi automatic if you are familiar with IWWCM Java API and Liferay Web Content API (Journal in code). With WPS you are probably using LDAP for your users so that will be simple just configure Liferay to import users from that LDAP. #4 is mostly manual work but you can at least get the members from LDAP if you are using groups.

Agree, there are many IBM users using iNotes portlet. It may also be worth the cost to replace Notes as well.
