Hi Luke, 
 
Thanks for contacting Syncfusion support.  
 
No, generating a new license key won’t invalidate the old key. You can use that old license key for that respective version. 
 
If you are upgrading the Syncfusion Nuget packages from v18.4.0.* to v19.1.0.*, you must generate and register the corresponding v19.1.0.* platform and version Syncfusion license key in your application. 
 
Note: 


You should not use v18.4.0* packages with v19.1.0.* license key,
You should not use v19.1.0* packages with v19.2.0.* license key,

Find below the knowledge base article to know about which version license key should use in application,https://www.syncfusion.com/kb/8951/which-version-syncfusion-license-key-should-i-use-in-my-application   
 
Let us know if you’ve any concerns.
