Goal

Qn1:Is it okay to mix collations in MySQL Server?

Qn2:Is it not permitted to have different server collation with the databases in MYSQL?
For example, user database is using utf8mb4_0900_ai_ci but server is setup to use utf8mb4_unicode_ci.

Qn3:If I have a database that is already setup with collation_server=utf8mb4_unicode_ci can I change it without needing to restart the mysql instance?
