How to go about updating/upgrading uniserver 5.7.4 Nano to 7.0.1 Orion?

You cannot upgrade a 5.7.4 to be a 7.0.1 they use different components.

 

If you mean how to copy a website from 5.7.4 o 7.0.1 that’s relatively easy.

 

Start 5.7.4 make a note of all your databases export these and then stop servers.

 

Extract 7.0.1 to a new folder and start servers.

Create databases as noted above. Use the above exported file/s to import tables.

Now copy your site/s from 5.7.4 folder www to 7.0.1 www folder.

What if directly i replace/overwrite the uniserver old files with new version? will it work?

 

 

How can i start two mysql service(old and new) simultaneously?

Not a good idea to overwrite one version with another. Configuration files mismatch (paths will be different) there may be other issues.
