The removal of older currency notes from circulation is a standard international practice, the RBI said.
The central bank is already withdrawing pre-2005 bank notes in a routine manner through banks as they have fewer security features than those printed subsequently.
In the Reserve Bank's view, the volume of bank notes printed before 2005 that are still in circulation is not significant enough to affect the public in a large way.
"The notes printed prior to 2005 will continue to be legal tender," it said, adding that even after July 1, any number of these old series notes can be exchanged by people at bank branches where they have accounts.
The RBI said it would continue to monitor and review the withdrawal of old notes so that the public is not inconvenienced.
The central bank announced the withdrawal of pre-2005 bank notes from the public in a January 22 statement.
On Thursday, RBI Governor Raghuram Rajan said the order was not an attempt at demonetization nor had it anything to do with the forthcoming general elections.
