My Gurugram upgrade: Found a tax hack!

Planning my 3BHK upgrade from my current 2BHK in Gurugram, I just realized something crucial about capital gains tax. If you're selling your existing property and buying another, Section 54EC bonds can be a massive saviour. Considering 3BHK prices on Golf Course Extension Road or Dwarka Expressway are easily ₹2 Cr+, this hack is crucial. Anyone else used this for their upgrade?
