# MySQL warnings when using SQLite

 * On a site running in SQLite mode, but which used to be a MySQL site (and still
   has all the old MySQL configuration), the health check screen is showing me a
   warning about my MySQL server:

 * The warning is probably correct, but since I’m running in SQLite mode, it’s also
   irrelevant.
 * (A different issue that might be “interesting” later on: `wp db cli` on a SQLite
   site still takes me to the old MySQL database, instead of launching an instance
   of `sqlite3` or similar. But that’s probably a wp-cli issue rather than a Performance
   Lab issue.)

 * Nice observation. I’ll need to check this with the team, however, I do believe
   this is more a wp-cli issue, given I expect the same would occur if defining 
   a SQLite database without the Performance Lab plugin. I don’t see any official
   support. I’ll report back to you here after checking this. Thank you.

 * [@desmith](https://wordpress.org/support/users/desmith/) Just to keep you informed
   on your WP CLI query with SQLite, I don’t see any official support at this time.
   There may encounter some potential solutions, [including this one](https://github.com/dumblob/mysql2sqlite).
   As these are untested you may wish to experiment on a test site only.
 * Let me know if you have any further questions on this.
