OS version checks will fail >= v10.x in upgrade-2.x.sh

[kb2ma]

Presently in upgrade-2.x.sh, the checks for $target_version and $VERSION use the regular expression in the example below, which fails when the major is >=10.

Try this script:

version=$1
case $version in
    [2-9].*|2[0-9][0-9][0-9].*.*)
        echo "OK"
        ;;
    *)
        echo "Fail"
        ;;
esac

Example:

$ ./test-case 2.0.1
OK
$ ./test-case 2024.1.1
OK
$ ./test-case 10.0.1
Fail
