Im not quite sure I understand what your getting at. But, honestly, I dont think moving to mars is the solution to a dying sun. It would have to be moving out of our solar system to a younger star. If we move to mars, we're just delaying the problem. However, if we become able to move between solar systems, then we will have conquered the problem of dying stars, atleast temporarily until theres no stars left

Ok, then. But until we find way to travel at speed of light or "faster" mankind will need to grab anything to survive.
of course travelling at speed of light for mankind will be nearly impossible .... at this point we are at fantasy level... but who know's ...
note: i didn't said our sun is dyeing,(ok. we know that's a fact every day for all stars..i.e., one step closer to the end) i was trying to say that mister "mankind" here, could find way (like in nasa statement) to accelerate brightness/power of the star to heat up a little more mars and fry earth (like venus)... then man could survive in mars... this could be a complete nonsense but, in the field of imagination everything is possible...right ?

The real question is did life on Mars last long enough for a technically advanced civilization to exist?
Nasa 2003 article, Life on Mars
In the past, Mars was much different than it is today. Liquid water used to flow on the surface, as shown in this picture. Both the Earth and Mars should have been frozen in their early history because the sun was weak at first, but both planets show that water was flowing, which suggests that they both must have had thick atmospheres in place to keep the surface warm. In this environment life may have once existed.
The atmospheres on both planets came out of volcanoes. There were not many volcanoes on Mars, and those volcanoes were never very active. Compare this to the Earth where volcanism continues today.
The volcanic eruptions produce a lot of water. The water eventually falls to the ground or into the oceans. Mars is small, and so cooled off very rapidly. Mars was sufficiently cold for water to be absorbed into the ground and freeze like tundra in the Canadian northwest. Today scientists estimate that a large amount of water is frozen into the surface of Mars. They estimate this happened by 2.8 billion years ago.
So it is not likely that Mars will become a haven for life in the future...unless it is life unlike that which we know?
2.8 Billion years ago on Earth, the first signs of life were just evolving, so I'm guessing Mars would be at a similar process for life at the same time.
Or not?

Who knows, maybe even some bacterial or fungal contamination could have escaped from one of our rovers and is currently enjoying the spoils of a extremely huge ecological niche on mars!

NASA has thought there was life on Mars for years. Here's an article from 2005 on the NASA site stating evidence of primitive life on Mars they found in a meteorite.
Don't you just love how everyone seems to ignore this and instead continue on with their own "theories" and speculations regardless of what NASA has already said?
