CHAPTER 1.2 Flashcards
In-Place Upgrade
Very simple. Not Technical Skill required
* Almost automated with Windows
Update Assistant
* Allows you to return to the previous
system version.
In-Place Upgrade Cons
Windows tries to bring everything from
the old version to the new version
* Accumulation of many old and unused
files, registry entries of certain uninstalled
programs, and all other types of
garbage.
* Some programs may not be compatible
with the new version
Clean Install
- A fresh installation is a good way to start
over. - A clean installation will only install the
apps you need and re-control your system apps, starting with a clean
Windows Registry.
Clean Install Cons
All data will be wiped off.
* You need to back up your personal files
and create an installation media with
Windows installer.
* Requires some technical skills
* Need to spend some time re- personalizing your server.
Plan the in-place upgrade [1/2
Verify that your VM ins tance meets the s ys tem requirements for Windows Server 2019 and has s ufficient free dis k s pace.
* Review the Windows Server 2019 and Micros oft Server application compatibility lis t.
* Verify that you aren’t affected by features removed or planned for replacement in Windows Server 2019.
* Verify that any of your cus tom or third-party s oftware is compatible with Windows Server 2019.
Plan the in-place upgrade [2/2]
Downtime: Depending on the configuration and software installed, the upgrade
might take an hour or longer. During the upgrade, access to the services is limited
Downtime
Services are unavailable to users
* Remote Desktop Protocol (RDP) is not available
* There are limited ways to check the upgrade progress and the time remaining in the upgrade
Plan the in-place upgrade [2/2]
Risk: Depending on the configurations of your existing instances and the installed
software
Risk:
The upgrade can fail
* Some configuration options can be overridden
* Incompatibilities can cause your workload to malfunction on the upgraded
instance
Windows Server
Core
Server Core is the best installation option for production use and with
Windows Admin Center remote management is highly improved.
Windows Server
Core with Server
Core App
Compatibility
FOD
Workloads, and some troubleshooting scenarios, if Server Core doesn’t
meet all your compatibility requirements. You can add an optional
package to get past these issues. Try the Server Core App Compatibility
Feature on Demand (FOD).
Windows Server
with Desktop
Experience
Windows Server with Desktop Experience is still an option and still meets like
previous releases. However, it is significantly larger than Server Core. This
includes larger disk usage, more time to copy and deploy and larger
attack surface. However, if Windows Server Core with App Compatibility
does not support the App, Scenario or Administrators still need the UI, this is
the option to install.
Nano
Server
~200MB Nano Server is great for new applications for example for .NET
Core applications. This image is the smallest of the Microsoft
Windows container images. It is lightweight and fast.
Windows
Server
Core
~3.3GB The Windows Server Core image offers the same application
compatibility like the Windows Server 2019 Core Installation
option.
Windows
~8.0GB The Windows container image, Microsoft is offering a new
option for applications who need more components which are
not included in Windows Server Core, like DirectX or proofing
support.
Desktop Experience
- Full server installation
- All server roles and features are supported
- GUI support
Server Core (Default)
Server Core (Default)
* Only essential components and services are installed
* No GUI
* Managed locally using sconfig.cmd and PowerShell commands
* Advantages :
* Less resource intensive
* Less downtime due to fewer patch and restarts.
* Reduced attack surface due to lesser software installed.
NANO Server
- No Graphical User Interface
- No local logon capability
- Only support remote administration
- Only supports 64-bit applications, tools, and agents.
- Advantages :
- Faster performance
- More stable and secured
- Uses less resources
- Requires fewer updates and restarts
- Optimised for cloud and virtualized environment
Configurations to be performed after installing Windows
Server:
Configure the IP address
* Set the computer name
* Join an Active Directory domain
* Configure the time zone
Windows Deployment Services
Enables network-based installations
* Simplifies the deployment process
* Supports deployment to computers with no operating system
* Provides end-to-end operating system deploymen
why perform in place upgrade
Servers meet minimum hardware requirements
Installed software support in-place upgrade
Need to retain data and security permissions
Need to keep existing roles, features, and settings
why perform migration
Server do not meet hardware requirement
Prevent existing issues from being carried forward to the new OS
Easier to troubleshoot installation failures.
what are the requirements for windows deployment services
AD DS – For authentication and access to the images
DHCP – assigns IP Address to the PC being deployed.
DNS – Provide name resolution
NTFS volume – Store the image
in place upgrade vs migration
what is the pros of in place upgrade
generally a straightforward process that takes lesser time and planning rather than a migration strategy
all server roles, features, data and application settings are maintained
in place upgrade vs migration
what are the cons of in place upgrade
more difficult to troubleshoot installation failures caused by existing server roles or applications
existing problems and configurations issues might be brought forward into new operating system
in place upgrade vs migration
what are the pros of migration
easier to troubleshoot installation failures
existing configuration and application issues are not carried forward to the new operating system
in place upgrade vs migration
what are the cons of migration
requires all applications to be reinstalled and configured
requires planning of migration of server roles
requires migration of data
requires the purchase of new hardware
