I'm using Altera Apex 20KE400EFC672 for years and it is time to phase out as it is no more available in market

You have a couple of options;
1. Contact a distributor that can find out-of-stock parts, eg., America II Electronics.
http://www.americaii.com/ 2. Contact a company that makes chip adapters, eg.,
http://www.arieselec.com/products/overview-correct-a-chip-sockets-adapters.htm The "problem" with a chip adapter is that you need to "adapt" the FPGA and its configuration source.
3. Determine the cost of a new board spin.
You may find that (3) is not really as bad as you think.
