I'm running the OpenCart 3.0.2.0, upgraded from 1.5.6.4 but I would like to reinstall my OpenCart, so I get rid of all the old files and modules that Ì don't need anymore ( and might cause problems)
If I backup my database, my images, my theme. Would this be as simple as
- backup db, theme db and files on server.
- Deleting the files
- Install OpenCart
- Importing the db on the fresh install,
- Install theme
- Importing the theme file.
- Putting back the image files
- Re-configuring the remaining extensions ?
Or am i missing something and am I in for a world of hurt

The db obviously will have redundant fields, not sure if that will cause problems ?
Starting with a clean db and somehow importing all relevant data sounds a lot more dangerous ( users, products, sales, downloads etc ...) or are there handy (failsafe) tools available for a task like this ?
Thanks for your help!
