What a ridiculous coincidence, I just did the right thing 30 minutes ago. There are no errors yet. In addition, protocols and services coexist with each other. You must specify an identifier for the new installation, which should be different from the old SQLExpress installation. I decided to name the new instance "SQLExpress2008", which is now listed next to the previous instance "SQLExpress".
Everything seems fine, although I have to admit that I'm an amateur when it comes to Microsoft SQLExpress. I hope that the answer to your question, if you have any specific problems, I could take a look at them.
