I am running into problems migrating. I am on PHP 8.2 and when I use the composer update command I get:  
Problem 1  
- laminas/laminas-httphandlerrunner[1.1.0, …, 1.2.0] require php ^7.1 → your php version (8.2.0) does not satisfy that requirement.  
- laminas/laminas-httphandlerrunner[1.3.0, …, 1.4.0] require php ^7.3 || ~8.0.0 → your php version (8.2.0) does not satisfy that requirement.  
- laminas/laminas-httphandlerrunner 1.5.0 requires php ^7.3 || ~8.0.0 || ~8.1.0 → your php version (8.2.0) does not satisfy that requirement.  
- cakephp/cakephp 4.3.0 requires laminas/laminas-httphandlerrunner ^1.1 → satisfiable by laminas/laminas-httphandlerrunner[1.1.0, …, 1.5.0].  
- Root composer.json requires cakephp/cakephp 4.3 → satisfiable by cakephp/cakephp[4.3.0].

I try to do the update with all dependencies but still have a similar problem.

Thanks for any help you can offer.  
Dave.
