While there is no doubt the default election timer could be adjusted, it is a separate issue from the clustered database upgrade failure.
No matter what value you set it to, your upgrade can still fail if the conversion time does not fit within a single election timer window. How to approach that fact is stream of work by itself which should be split out in a bug of its own.
Hello, Nishant, and thank you for the bug report.

One issue per bug, please :)
