Problems converting Centos 8 to Rocky Linux

[ctello-lentillas-si]

I have a VM machine in GCP with Centos 8.

When I try to run the script (migrate2rocky.sh), I get the following error:

Commands not found: grub2-mkconfig efibootmgr. Possible bad PATH setting or corrupt installation.

I check if the commands are installed and they are. I also check the PATH and it is set correctly. But typecommand seems don't find these commands:

[root@XXYYZZ]#  cat /etc/redhat-release
CentOS Linux release 8.5.2111
[root@XXYYZZ]# whoami
root
[root@XXYYZZ]# sudo bash migrate2rocky.sh -r
