 * I am recievng the following error when migrating from one site to another taht
   is hosted on godaddy:
 * > A problem occurred when attempting to process the following table (#113) wp_mailpress_usermeta
 * I didn’t have tis issue previously when migrating the same site to a different
   host.
 * I tried reverting both versions of WPMigrate plugin DOWN to version 1.3.6 (the
   only other version i have of the plugin) as suggested might have solved this 
   issue for other people experiencing this same error, but it still doesn’t work
   and then i get different errors.
 * So i am now using the most current version ofteh plugin, but experiencing this
   error.
 * Any help would be greatly appreciated.

 * sorry, the actual error referenced the tablw wp_posts, (not wp_mailpress_usermeta
   as indicated in my original post above). So i excluded that table from the migration,
   and now i get this error instead:
 * > WordPress database error: [Unknown collation: ‘utf8mb4_unicode_520_ci’]
   >  CREATE
   > TABLE `_mig_gwb_rg_form` ( `id` mediumint(8) unsigned NOT NULL AUTO_INCREMENT,`

   > datetime NOT NULL, `is_active` tinyint(1) NOT NULL DEFAULT ‘1’, `is_trash`

 * I deactivated all plugins, and now the migrations doesn’t stop at wp_posts, but
   throws the above new, long error when it hits wp_reg_forms
