Upgrade from ver 5.2 to ver 7

Is it possible to upgrade from dolphin 5.2 to ver 7? I need to move all users, about 15000 memebers

I think you would have to upgrade to each version that has been released.

Talk about a PITA...

If you don't care about photos, videos, groups, forums its not too hard to import *only* the users using MySQL

I would suggest just install the latest version it would be less painfull and could saved your money. After the install you can copy all user's using your PHPmyadmin..

Can you please tell how I can use phpmydamin to do that? Shortly

I assumed that you already have an access to  "www.yoursite.com/cpanel" scroll down click phpmyadmin.

Select the database for your old dolphin site and go to "Profiles" this is where site's member is located then hit "export" check the box  Save as file and press go.. After that run the member "SQL" files downloaded from your your old dolphin to your newly installed version.

If you need help  just pm me.

Hello Knarsa!

Simplest solution for migration in case when you need transfer only main fields ('NickName', 'Password', 'Sex', 'LookingFor', 'Email'):

0) Backup all old files and DB!

1) Copy old `Profiles` table with new name like `Profiles_old` to new D7 Database.

2) Execute next query:

INSERT INTO `Profiles` (`ID`, `NickName`, `Email`, `Sex`, `LookingFor`, `Password`)

SELECT `ID`, `NickName`, `Email`, `Sex`, `LookingFor`, md5(`Password`) FROM `Profiles_old`;

UPDATE `Profiles` SET `Salt` = CONV(FLOOR(RAND()*99999999999999), 10, 36);
UPDATE `Profiles` SET `Password` = SHA1(CONCAT(`Password`, `Salt`));

For more serious content (more fields, profile photos etc) better to ask specialists for making migration script.

Regard

Do you know about some who can make a migration script or do you know about a migration script? 

This was a surprising topic to read.

Anyways, an Agent may be willing to create one for you (AntonLV?) if you pay the right amount of money.
