I am trying to understand how to upgrade a LTS8 installation installed with
composer create-project typo3/cms-base-distribution myProject ^8
to LTS 9.5.
When I follow the documentation and do
composer require typo3/cms-backend:^9.5 typo3/cms-core:^9.5 typo3/cms-extbase:^9.5 typo3/cms-extensionmanager:^9.5 typo3/cms-filelist:^9.5 typo3/cms-fluid:^9.5 typo3/cms-frontend:^9.5 typo3/cms-install:^9.5 typo3/cms-recordlist:^9.5 --update-with-dependencies
I get

Installation failed, reverting ./composer.json to its original content.
Shouldn’t my fresh installation not be all v8.7.19?
It seems there is no direct way on this major update. I finally ended up exporting the pagetree of my 8.7 installation as well as the db, created blank 9.5 installation with all extensions, imported the pagetree and imported the db. Since I only used major ext like georgringer/news and bootstrap_package I had no major prolbmes
