My website
ViperAlley is an extensively modified version of 6.2.3. In each Threads release since, I simply took the parts of the new verison I liked and merged it into my site.
With 6.4 coming out and including built in Calender features, improved polls and some other nice-to-haves, I'm thinking of starting over with a 6.4 release (or just hacking in the mods I like, such as the "viewing" mod I added already). However, I'm not exactly sure how I should go about this.
Since I would want to test and migrate over when I had the basics done; what would be the best approach for doing this without risking much downtime?
