    I have a question about the Transfer Tool in WHM. What happens if you use this tool to transfer a cPanel account from a LAMP server running outdated packages including MySQL 5.0 to a LAMP server running updated packages including MariahDB 10.0?

    Will the Transfer Tool perform a MySQL dump and correctly import the database tables, accounting for the change in database versions?

    If not, what would be the correct method to transfer a cPanel account between servers so that the database will work?

    Hello :)

    There's no support to transfer accounts from that environment. You can see a list of supported control panels we support transfers from at:

    Transfer Tool - Documentation - cPanel Documentation

    You can manually create the account on the cPanel server and then import the database through phpMyAdmin or the command line. You can then use the database mapping tool to map a database to an account:

    Thank you.

    Thanks, we recently performed a transfer like this and now we're seeing some errors. Is there anything we can do if we've already done a transfer between a server running MySQL 5.0 to a server running MariahDB 10.0? Or do we have to scrap the new server and perform the transfer again following the process you provided?

    Yes, these are both cPanel servers located with the same hosting company. We just moved from one data center to a different one, still with the same hosting company.

    The hosting company performed the transfer using this tool. The major difference between the two servers was that the old one was running MySQL 5.0 and the new one is running MariahDB 10.0. The transfer seemed to be successful and the transfer log shows no errors. However, we've started to get 500 Internal Server Errors and the logs show a large number of database errors. We're trying to determine if this was caused by using the transfer tool to perform a transfer to a server running MariahDB 10.

    Could you provide the specific output you see in /usr/local/apache/logs/error_log when the website produces a "500" error message, in addition to the specific MySQL errors?

    Thank you.

    I checked /usr/local/apache/logs/error_log and there are no errors produced in that log when you get the 500 error.

    Here are the MySQL errors:

    Code:
    WordPress database error Table 'mrtllc_sfwd_store.WP_AFF_PAYOUTS_TABLE' doesn't exist for query select * from WP_AFF_PAYOUTS_TABLE where refid = 'asimetria' ORDER BY date and time LIMIT 20 made by require('wp-blog-header.php'), require_once('wp-includes/template-loader.php'), include('/themes/springboard/index.php'), the_content, apply_filters('the_content'), call_user_func_array, do_shortcode, preg_replace_callback, do_shortcode_tag, call_user_func, wp_affiliate_view_handler, affiliate_platform_affiliate_view_main, wp_aff_payment_history_view, wp_aff_show_payment_history, wp_aff_payments_history
    
    WordPress database error Multiple primary key defined for query ALTER TABLE wpsfstdev_affiliates_leads_tbl ADD PRIMARY KEY (lead_id) made by activate_plugin, do_action('activate_wp-affiliate-platform/wp_affiliate_platform.php'), call_user_func_array, wp_aff_platform_install, wp_affiliate_platform_run_activation, wp_affiliate_platform_run_installer, dbDelta

    This looks like an issue with that specific plugin. Do the errors go away when you disable it?
