Currently I am using a dedicated web server connected via private network to a dedicated database server to run WordPress. The database server is running on Centos 7 and mariadb 5.5.
I am considering to upgrade the web server to centos 8 and mariadb 10.3.
- Is it advisable to upgrade from mariadb 5.5 to mariadb 10.3 for wordpress? Would there be compatibility issues for existing WordPress database? What are the areas of concern I should be aware of.
- Is there a performance advantage for upgrading centos 7 mariadb 5.5 to centos 8 mariadb 10.3 for wordpress? Or I should stick to centos 7 mariadb 5.5 to avoid unnecessary trouble?
