as i could be moving from servers
what are the things i should do?
and most importantly what are the things that i should avoid?
Try searching the board. There have been several requests on how to do this, even just today.

- you need t0 backup database (using phpmyamdmin or mysqldumper or any mysql tool on your hosting control panel)
