I have an Joomla 1.5 old site with Community Polls 1.5.9.
I successfully migrated from Joomla 1.5 to Joomla 2.5 and now want to move Polls from old site to new Joomla 2.5 site with Community Polls 3.0.3 installed on it.

What should I do?
I need to export some tables (which one?) from J1.5 database, import it to J2.5 DB and rename?

Or I need first to upgrade Community Polls on old J1.5 site and than export/import some tables to new J2.5 DB?

Thanks.
P.s: sorry. Wrong category :(


Updated:

I did like that.
1. Exported jos_jcp_* from J1.5 an dimported it to J2.5. Rename all jos to j25.
2. Install CP
3. Install CJLib

and get this error at admin panel (at CP page):
