Upgrade is a process in which the existing product is added with Patches or service packs . This changes the Version of the Product . Typically upgrades are done to remove bugs from the Product to add features to the existing product so that users feel comfortable to have that product and utilise it to the fullest .
The Upgrade or patch will first check if you have the product installed on the machine and only then proceed with the installation .
for example Upgrade would be from Moss 2007 Sp1 to Sp2
Now Lets Understand Migration .
Migration is the process of replicating applications from one product in another product
Like Sharepoint 2007 to Sharepoint 2010 .
it can also be Moss sites Migrating to the Websphere environment or visa versa .
For an Migration you need not have the base product installed on the machine . it would be a fresh product installation on which migration has to be done .
Note - I have tried my best to explain the above topic . just incase if you feel something is missing or any corrections has to be done . Feel free to get in touch with me it would be much appreciated .

Hi, waht is the difference between migrating using "Attach" and "detach" databse method and migration using tools ?
ReplyDeleteHi ,
DeleteThanks for checking my blog .
Microsoft has come up with 2 methods .
In-place upgrade and Database attach upgrade .
practically the only difference would be moving the customisation or keeping the same config db and upgrading it to the next version .
inplace has to be done on the server on which we already have moss 2007 installed and a running farm
as you know for 2010 the hardware and software requirements are different so it would be a double process of moving the farm on the new hardware and then doing a upgrade .
Sees still it depends on your thought process .
large farms always try to go for a Database attach upgrade
which is much more sturdy than the other .
