> [@Isage](#): > > Is there not an access problem to the Gladys server, which might perhaps explain why I get stuck on the web page « We are configuring your Gladys Assistant installation… » when I try to migrate to an SSD? I confirm what @Tlse-vins said, this is a current limitation of Gladys. When you delete a device, Gladys must delete all the states of that device. However, if you have many states (probably your case), and your disk is not very fast (as is the case with a micro-SD), this deletion can be long, and is currently blocking, which makes Gladys unavailable during the deletion. This is a real problem that I started to fix in Gladys Assistant v4.10.2 by improving the deletion of states, but only for the « Yes, keep states » button, not yet for the « Delete » button of a device. (See =\> [Gladys Assistant v4.10.2 est disponible avec des corrections de performances et un bouton nettoyage de la base!](https://community.gladysassistant.com/t/gladys-assistant-v4-10-2-est-disponible-avec-des-corrections-de-performances-et-un-bouton-nettoyage-de-la-base/7555?u=pierre-gilles) ) When you delete a device, in your case it’s better to wait, and it can be long on slow disks… Sorry for the bad experience you’re having, you are unfortunately hitting several « known » limitations of Gladys in a row, I can imagine your frustration! --- _[View the full topic](https://community.gladysassistant.com/t/difficulte-a-migrer-mon-instance-vers-un-ssd/7583)._
