3. What Should You Do Upgrade Successfully
3.5 Make One Change at a Time by the Right Order
Determine the Right Order of The Upgrades in Your PHP Environment
1m11s So the next step is to determine the right order by how you will be applying the changes in your environment.
If you need to apply different changes, not just the PHP version, you need to determine which tool you will upgrade first because certain changes have consequences so they need to be done first.
Change Your PHP Version First
1m42s What I suggest is that you change the PHP version that you are using, first.
Change Your Web Server
1m48s Next change your Web server if necessary.
Change the Database Server
Later, you can change the database server.
Change the Email Server If Necessary
Do the Operating System Upgrade
2m03s Finally, I suggest you do an operating system upgrade but probably that operating system upgrade also upgrades all the other tools that I mentioned.
So if you plan to upgrade the operating system, probably just do that upgrade and verify that the versions of the software that you need are already there.
If they are not there, you need to do the upgrade later, OK.
If your PHP applications have crucial features and must keep working after an upgrade, those are the first features you need to test.
Usually, those are features that deal with delicate aspects like finances, and people's data security, including identity and health data.
