Dear All,

Am going to do migration of database from one version to another., is there
any article or any other document explaining the possibilities and other
things.

Further Explanation:

I have a database in postgres X.Y which has around 90 tables, and lot of
data in it.
In the next version of that product, i had some more tables, so how to
migrate that,. there may be 150 tables., in that 90 tables, 70 may be the
same, 20 got deleted, and 80 may be new., i want the 70 tables to have same
data as it is.,
