Upgrading from 3.0.24 to 4.0.13

Hi

I have upgraded my AWS EC2 zabbix server to 4.0.13, but now my RDS instance needs upgrading. I can't find any notes regarding this. When I go to the web GUI, I get the attached.

The new (4.x) frontend connected to database, which is not-yet upgraded from 3.x to 4.x version.
Start the new 4.x Zabbix server, it should do the database upgrade and the frontend should start working normally.

Would it take a long time before I notice anything?

This is what I have installed on my zabbix server - an ubuntu EC2 instance:

zabbix-agent/unknown,now 1:4.0.13-1+trusty amd64 [installed]
zabbix-frontend-php/unknown,now 1:4.0.13-1+trusty all [installed]
zabbix-get/unknown,now 1:4.0.13-1+trusty amd64 [installed]
zabbix-java-gateway/unknown,now 1:4.0.13-1+trusty all [installed]
zabbix-release/unknown,now 1:4.0-3+trusty all [installed]
zabbix-server-mysql/unknown,now 1:4.0.13-1+trusty amd64 [installed]

And I have an AWS RDS instance running the mysql DB. I don;t know how to upgrade this to the same version as the server. Apologies for asking such simple questions.
