Archiving Cyclic Projects without Losing the board

I use projects in Monday Work Management to manage development of products. The products undergo a 2 year revision cycle and then rest for 2-3 years before we start them again. In order to update the new milestones but keep the old data my thought is that I must duplicate each board, archive the original board, and then update the milestones in the copy. Is there a better way to do this? I am trying not to have to recreate the board or change names on the projects. Thanks.
