No. Replace the liner.
We used Garrett Vinyl Pools they have been around for years.
what you can do in this situation depends on what is under the vinyl liner now.
To fix a detached vinyl liner from its spot on an above ground pool, the water will have to be drained from the pool. Then, a marine patch can be placed on the area to re-attach the vinyl to the place where it came apart. Allow this to dry thoroughly before refilling the pool.
There is special adhesive for this,sold in pool maintenance stores.
As long as the vinyl liner pool is inground, it can be converted. But you'll probably have to remove all of the vinyl pool elements until you have reduced the pool to a big hole in the ground and then start from there. All it takes is time and money!
The walls of some above ground and some inground vinyl liner pool kits are made of aluminum.
Some pool companys are not in business. most all inground pools have the same size treads..
If you have water behind your vinyl in ground pool liner, you should first lower the water in the pool to normal levels if it is over-filled. Make sure that the vacuum pipe is clear, unclog it if it is not. Once it is unblocked let the water from behind the liner flow out.
Installers use vinyl liners to create inground pools without pouring concrete. Here's an overview of the topic http://www.poolandspa.com/page232.htm.

Now a days 3 and 4 are the most common inground installs. 1 and 2 are usually pools that are 30 + years old although you can still have them done that way. In South Alabama the cost of a 20 *40 vinyl pool will cost around 18 to 22 thousand
