نصب ورژن جدید لاراول

با سلام . من برنامه ی زمپ و نسخه ی جدید لاراول رو نصب کردم .
حالا برای اجرای پروژه هایی که با نسخه ی 7 لاراول نوشتم مشکل دارم .
اولین کار اینه که میخوام دیتابیس را با migration بسازم اما کلی خطا بهم میده .
در این موارد باید چکار کرد .
خطاها اینه :

PS C:\xampp\htdocs\mysite\shopping> php artisan migrate

بهتره این طور سوالمو بگم که :
نسخه ی جدید xampp,composer و لاراول 9 رو نصب کردم .
حالا پروژه ی قدیمی من که با لاراول 7 بود و همین طور php 7 دیگه کار نمیکنه.

مثلا وقتی میزنم composer update میگه :

    - Root composer.json requires php ^7.2.5 but your php version (8.1.6) does not satisfy that requirement.

کارهایی که انجام دادم :
اول در composer.json بطور دستی ورژن جدید php رو وارد کردم .

php : 8.1.6
سپس دستور composer update رو اجرا کردم.

اما بعد از وارد کردن php artisan خطاهای پست اول رو میده
