April 2020 - Upgrade to CentOS 7.8:
Upgrade worked with no issues
September 2019 - Upgrade to CentOS 7.7:
Best practice is to clone a VM before upgrading so you have a clean starting point.
Got these errors upon trying to upgrade:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Solution:
# yum remove vlc
Then Install VLC
Update hostname to centos7.7
Then, test VM upgrade from CentOS 7.6 to 7.7 worked OK and got full-screen graphics with Guest Additions v 6.0.10. 2 other VMs upgraded OK, but Guest Additions v6.0.12 will not install properly. Newest kernel is kernel-3.10.0-1062.1.1.el7.x86_64 but had to boot into 3.10.0-957.27.2.el7.x86_64 to get full screen display to work.
Problems:
Guest Additions troubleshooting:
Python3 fix to use EPEL instead of IUS repo:
# yum remove python36u # yum remove ius-release # yum install python3 # yum install python3-devel

Rebooted, updated Guest Additions running on VirtualBox v5.2.22 but full-screen (Host+F) is not working properly.
* An option may be to use Kernel version 4)
Video problem discussion solved in test build.
But Mouse focus problem crops up again. Also see ticket 17827
Note: Bug report for mouse problem in RHEL and CentOS has been submitted
I added comments about the video problem to ticket 18093.
September 2017 - Upgrade to CentOS 7.4:
Best practice is to clone a VM before upgrading so you have a clean starting point.
Right before upgrading to v7.4 I got an error due to a conflict between gstreamer1-plugins-base-1.10.4-1.el7.x86_64 and gstreamer1-plugins-bad-free-1.4.5-6.el7_3.x86_64. This seemed to be caused by the "totem" application but it was resolved in CentOS 7.4. I found a temporary workaround in 7.3 was to remove the RPM gstreamer1-plugins-bad-free which allowed other packages to update:
# yum remove gstreamer1-plugins-bad-free
However, when CentOS 7.4 became available I got another error:

Removing this package allowed the upgrade to proceed:
# yum remove usbmuxd

After I updated to CentOS 7.4 I was able to reinstall totem without any issues.
VLC also installs OK and it uses the Nux Desktop repository.
An updated mate-themes RPM was released to fix badly-formatted pull-down menus (ex. mate-terminal).
Mutt stopped sending emails on cron and it was reported on Stack Overflow:
Bad IDN in "from": 'machine_name'
The RHEL 7.4 package is mutt-1.5.21-27.el7.x86_64 (in CentOS 7.3 it was mutt-1.5.21-26.el7.x86_64). Downloaded and installed mutt-1.6.2-1.fc22.x86_64.rpm from rpmfind.net as a workaround.
On the host machine, samba was upgraded from v4.4 to v4.6 which prevented authentication to the shares.

When first setting up the VM with Oracle VirtualBox, you may see “failed to access perfctr msr” error appears at initial boot. But the program continues installing normally after several seconds.
RedHat 7 Disk Partitioning Guide
Disk partitioning used the following, where system RAM was 1536 MB and total disk size was 15GB:

yum install wget
Follow instructions to Install MATE Desktop
Note that there might be a problem with installing the "Development Tools" group. If so, follow these instructions:
# yum groupinfo -v "Development Tools" # yum groups mark install -v "Development Tools" # yum list updates (note: you will see a bunch of packages to install now) # yum -y update
Continue with the rest of the MATE desktop installation steps.
Proceed with CentOS 7 Migration Notes
Before migrating users' $HOME, make a test user on CentOS 7 and on CentOS 6. Login to each graphically. See if the hidden files have changed format and use that info when migrating the $HOME directories.
Remove open-vm-* packages as they are not needed on non-VMWare machines:
After everything is configured make a clone and deploy as needed:
