Migrate from Magento 2.3 to Magento 2.4

Question

I have a brand new Magento instance (2.4) and an old instance (2.3) with product/order/cms/theme data.

I would like to migrate the data from Magento 2.3 to 2.4, is there any way to do this?

I have tried upgrading the existing 2.3 (cli) site but running into a lot of errors - and to move to a new set up, where I know 2.4 is working, seems to be a sensible option, but is it possible?

Initially update the magento using these commands

composer require magento/product-community-edition=2.4.0 --no-update composer update

Moreover Enable the developer Mode and run deployment php bin/magento deploy:mode:set developer php bin/magento setup:upgrade php bin/magento setup:static-content:deploy -f php bin/magento setup:di:compile php bin/magento cache:clean
