SPUpdatedConcurrencyException: An update conflict has occurred, and you must re-try this action

I was moving site from One server farm to another , completed backup of source site successfully,everything was working fine till the Murhy's extended Law got into effect ......

"If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong"

Anyways , i started restoring the site and bumped into this error. I had no clue why even this popped up . Tried multiple time but same result .Started search for error resolution and it was good to see that there are more victim of this issue.

So i tried one of the suggested approach and it worked ......

Well i just completed the site restoration and hope i dont fall victim to another law which i read somewhere and i felt it's kind of funny :

"No matter how perfect things are made to appear, Murphy's law will take effect and screw it up"

ENJOY!!!!!
