When using MH you MUST match the bulbs to the ballast. So if you want to upgrade you must replace the bulbs and the ballasts.
Since we are talking about DE bulbs you must also upgrade the socket. The mounting method for 250w bulbs is completely different from 150w bulbs.
In addition make sure your fixture can deal with the additional heat. 250w DE bulbs run extremely hot.
Since you are going to this much trouble, be sure to purchase electronic ballasts. They will consume far less power, and pay for themselves in 1 to 2 years.
Now one thing you are going to notice is that you are replacing almost everything, except the basic housing. This is a case where it might be a lot easier to just get a new fixture, and sell the old one. You might even come out better, cost wise, doing this than you would doing an upgrade.
