I tried to install the upgrade tool but am unable to get it.
The only way to get the tool is through your RedHat account manager. You will need a RHEL subscription first.

Re: Problem boot CentOS after migration from VMWare to Hyper-V

Btw, rebuilding the initramfs is the most important thing. Because HyperV VMs use the MS bus and devices, the necessary drivers are not present in the initramfs you have on your VMWare systems. Rebuilding initramfs in single user mode will autodetect the drivers and add them.

Re: Problem boot CentOS after migration from VMWare to Hyper-V

HyperV is a bit odd. The VMs don't look like PCs, there's no PCIe bus and all the devices are MS specific and the Gen2 EFI implementation is a bit quirky. However, I successfully migrated our setup from VMWare to HyperV a year or two ago, everything I did has already been mentioned above but from me...

Re: Possible networking issue in CentOS 7.6

I suspect you have a hardware issue here. If you haven't got another NIC handy you could try unloading/reloading the driver to give the card a poke but there's probably not much you can do.
Sorry I can't offer anything else.

Re: Make cannot access stdlibs

[vandam@sadlo build]$ cmake3 -D CMAKE_CXX_COMPILER=/opt/rh/devtoolset-8/root/usr/bin/gcc

Yes. You can do that with a kickstart script in your .iso image.

Re: mirror external repositories

The -n flag is useful as well. Only takes the latest version.
