What is difference beteen Migration and Upgrdation?

Answer Posted / phani kiran sai

Migration:
There are various situations for migration
1. LAUNCH, GO-LIVE, DEPLOYMENT.
A situation or a birth of PROJECT is known as LAUNCH,
GO-LIVE, DEPLOYMENT. Starts from Development -> Test ->
Production.

2. DB-REFRESH.
When we need to take back the server and its functionalities
from PRODUCTION SERVER to TEST SERVER and back again to
PRODUCTION SERVER is known as DB-REFRESH.

3. MOVING FROM OLD HARDWARE TO NEW HARDWARE.
Every hardware is subject to END OF LIFE. In such
situations, we would move the entire server from OLD
HARDWARE to NEW HARDWARE.

4. MOVING BETWEEN DIFFERENT DATA CENTERS.

5. CONSOLIDATION PROJECT.
CONSOLIDATION is a process of gathering all the NON-CRITICAL
databases over individual servers and managing them in a
single high scalable server.

FROM THE ABOVE SITUATION, WE CAN CLEARLY IDENTIFY THAT WE
ARE NOT EFFECTING THE VERSION OF THE SQL SERVER SOFTWARE.

Up-gradation:
UP-GRADATION is a process of INSTALLING a newer version on
the existing SQL SERVER SOFTWARE. [E.G HOTFIX, PATCH,
SERVICE PACKS, VERSION UPGRADE]
There are two types of UP-GRADATION
1. IN-PLACE UP-GRADATION
2. SIDE-BY-SIDE UP-GRADATION
