I have an old Joomla 1.0 book with akobook installed.
So migrating was VERY easy, as Easybook Reloaded is a successor of akobook.
I copied my old table to the new database, installed Easybook Reloaded.
My new database contained both tables: old mos_akoobook and new j25_easybook
Next I executed the query:
INSERT INTO j25_easybook
SELECT
gbid as id,
gbip,
gbname,
gbmail,
0 AS gbmailshow,
gbloca,
gbpage,
gbvote,
gbtext,
FROM_UNIXTIME(gbdate) as gbdate,
'' as gbtitle,
NULL as gbcomment,
published,
gbicq,
gbaim,
gbmsn,
'' as gbyah,
'' as gbskype
FROM `mos_akobook` WHERE 1
