[news.eclipse.technology.epf] Migration to newever library version

["Roman Smirak" <roman.smirak@xxxxxxxxxxxxxxx>]

Hi,

     I have just downloaded latest version of OpenUP library and tried to 
migrate my plugin to this.

My plugin has been developed on OpenUP 0.9 distributed with Composer 1.2 M3 
(I guess - can I check it somewhere? Plugin.xml, etc.)

I started EPF with OpenUP 1.0-RC3-20070720 and imported my plugin; and it 
didn't work - workspace/.metadata/.log shows:
    java.lang.NullPointerException

However, next time it worked (I just deleted workspace, copied library and 
imported my plugin again) and so I cannot reproduce it. I'm putting it here 
just FYI.

Now I see couple of errors telling me:

Does it mean that my plugin contributes to some elements which have changed 
or don't exist anymore?

Question: what are your suggestions/recommended practices for the migration?
