Allardyce is keen to hang on to his quality players, especially as Rovers appeared to have suffered from the loss of goalkeeper Brad Friedel to Aston Villa and midfielder David Bentley to Tottenham in the summer.
"Mark Hughes (former Rovers boss) did similar at Blackburn as I did at Bolton; he got a lot more talent than when he first came and grew that over years," Allardyce told the Lancashire Telegraph.
"We have lost two of that talent and we have to make sure we don't lose any more.
"If we do we have to replace it with more than what you lose. We are better keeping our better players now than selling them.
"I think the planning (for next season) is in its infancy but I prefer to put it on hold as much as I can.
"Certain aspects have to be talked about but it is only on a minimal basis [because] it is about making sure we stay in the Premier League.
"That will put us behind in our planning but I think that is the most important thing, concentrating on game to game and getting out of the bottom three."
