Database import

Hello,

my client needs to import old database with questions and replies to the easy discuss.
It is a database, where questions and answers are placed separately to two tables.

Each table has, as I check, all fields which are important to easy discuss, but I do not not, how are questions and replyes connected (in according to fields I saw).

First, I will import users so I will have user id.

Each question has its creation time, user id, category, etc, but as replies have its own id and also id of the question to which it bellongs to, I am confused how it is managed in easy discuss.

Thank you in advance

Best regards
Pavel Kurfürst
