ANOTHER TYPE OF WINDOWS INSTALLATION:
A clean installation of windows 8.1 is required before installation windows 8.1 by using migration scenario, followed by the migration of the user setting data from the older version of windows operating system to windows 8.1. Depending upon your business environments, use two migration scenarios : side by side migration and inplace migration also known as refresh computer scenario.
Both migration scenario require a clean installation of windows 8.1. Migrating previous configuration from an old operating system requires to moving files and settings to clean installation of a windows 8.1 operating system.
Evaluating a migrating scenario
In any potential upgrade scenario, there might be certain variables that favor a migration. However, there also are disadvantages.
Following are the advantage of migration scenario:
· Creates more stable and secure desktop environment by cleaning up existing workstations. Avail the opurtunity for a fresh start, which is a significant advantage when creating a managed environment.
· Because of no remnant file and settings, it avoids the performance degradation issues associated with an in place upgrade scenario.
· Allows for the installation of any edition without any concerning about previous edition.
· Before installation, provides the oppurtunity to reconfigure hardware level settings, such as disk partitioning.
· Help in preventing the migration of viruses, spyware, and other malicious software. Use hardened security settings such as group policy and security templates.
Following are the disadvantages of migration scenario:
· To save and restore user settings and data requires migration tool, such as windows easy transfer or the user state migration tool (usmt).
· Requires the reinstallation of applications.
· Requires the storage space for the user settings and files to be migrated.
· Reconfiguration and settings of applications might affect user productivity.
Steps for performing migration
Migration scenario includes following steps:
1. Back up a computers entire hard disk.
2. Save user settings and data for migration.
3. Perform a clean installation of windows 8.1.
4. Reinstall applications.
5. Restore user settings and data.
When planning a migration, determine the method to move from existing data to the newly deployed operating system. The selection of the methods depends on the available tools and resources. The method that you use depends on the tool and resources that you have available . In enterprise environments use configuration manager to automate the migration process. Various factors such as whether the user is moving to a new computer or will be using existing computer with new operating system also decides the migration method. Following are the types of migration:
· Side by side migration. In a side by side migration, data and settings are moved from the source computer to desitnation operating systems. In most automated side by side migrations, migration data is transmitted accross to network. Using removal storage devices the migration of the data can take place only while performing migration manually.
· Wipe and load migration. In a wipe and load migration, migration data is stored and moved to a safe location such as , network share folder. After this, the source operating system is wiped from the host and then, finally restoring the source operating system data from the safe location to the destination operating system.
· Operating system refresh. The migration type is similar to a wipe and load migration. The source and destination operating system are the same in this migration. The migration is useful when upgrading to a new operating system service pack or when an error occurs while deploying the original operating system and an attempt to resolve the fault is not practical.
Choosing when to perform a migration
Decision of performing migration depends on following:
· Requires standarized environment: al system running a windows operating system require a standarized environment. A migration perform clean installation. A clean installation ensures that all application files and settings are reset and all of the systems begin with the same configuration. Migration retains user settings and data.
· Have storage page to store the user state : usmt introduces hard link migration, in which case you do need extra storage space. This is only applicable to wipe and load migrations.
· Plan to keep existing computer hardware: migration like wipe and load migrations help to continue to work with the existing computer hardware. There will be no need to replace existing computers.
