hello

We have detected that the new 4.0.5 version is available to download. Please click the link below to start downloading. After completing the download and replacing the files don't forget to run Upgrade routine again.
 
 
.
 
do i need to download any news file ? or all automatic?
 
I know i have to backup my mysql database, and make a copy folder of my website.
Any others SAFE procedure to make before upgrading ?
Anyone find any errors in upgrading procedure? I am using 3.6 enterprise edition
 
Thanks all !

I upgraded a multi-site installation and I upgraded from 3.6 to 4 and followed ViArt's procedures (and suggested safeguards like dir and db backups) and all went fine. Then have been manually applying patches as they became available.

Yes you need to copy new version files from there http://www.viart.com/Free_Evaluation_Download over your old files and then click on "Upgrade" button in your admin.
 
All SAFE procedures are described there: http://www.viart.com/upgrade_viart_shop.html
 
Please remember that version 4 has significant changes in structure that's why if you have a custom design or any customizations in the files they will not work on latest version.
 
If you have any questions, please contact us at https://www.viart.com/support.php

thanks five & vera
 
i tried to use the database dump tool from system db management but after i try and submit all fields
it start to process but after some mb, it give this error msg
 
Database error: Invalid SQL: SELECT event_id, order_id, admin_id, status_id, order_items, event_date, event_name, event_description, event_type FROM `va_orders_events`
MySQL Error: MySQL client ran out of memory
 
probably my database is too big, about 600 mb already ( but zipped only 46mb ), on ftp i see a .sql file only of 55mb ,
 
for database backup i can use mysql phpmyadmin.
at new year will try the upgrade procedure and hope don't see any errors !
