Title: Problems with migration Last modified: August 30, 2016 --- # Problems with migration * [theprotoss](https://wordpress.org/support/users/theprotoss/) * (@theprotoss) * [10 years, 9 months ago](https://wordpress.org/support/topic/problems-with-migration/) * Hello. * I’m experiencing problems during a wordpress website migration. * So, to do the migration, I exported the mysql database from the old installation, I created a new database on the new server, with the same db name, username and password, and I imported it. * I used the mysql40 compatibility mode of the phpmyadmin to export the database because, if I do the quick-standard exportation, when I try to import the database, phpmyadmin on the new server returns an error (unknown collation ‘utf8mb4_unicode_ci’). * Then I copied all the website files from the old hosting webspace to the new one. * The website on the new server runs correctly, I also installed plugin updates and the new wordpress version, but the graphic is bad (some people said to me that the css is not loading correctly). * What have I to do? * Thanks, * Carlo Viewing 9 replies - 1 through 9 (of 9 total) * [Alen](https://wordpress.org/support/users/alenma/) * (@alenma) * [10 years, 9 months ago](https://wordpress.org/support/topic/problems-with-migration/#post-6510766) * Hello Carlo, * I would suggest to use this plugin: [https://wordpress.org/plugins/wp-clone-by-wp-academy/](https://wordpress.org/plugins/wp-clone-by-wp-academy/) * Thread Starter [theprotoss](https://wordpress.org/support/users/theprotoss/) * (@theprotoss) * [10 years, 9 months ago](https://wordpress.org/support/topic/problems-with-migration/#post-6510769) * Thank you Alen!
