How to migrate to 0.8.6j from 0.8.6e version

[jga]

I need your help about this.... I try to migrate cacti database , I perform new install, but when I get cacti database backup from mysql, cacti says, I not have any database configured!, If I delete the line that have version number of cacti on config.php or only delete these numbers "0.6.8.j", it runs fine, but I'm not shure if database structure of "e" version is the right structure for "j" version, obviously it number is considered for many subprograms inside cacti

thanks
sorry about my poor english
