yes, and no
your main functions (stuff like onLogin, onUse, onSay, etc) will have to be updated
some subfunctions (the functions you script with like doPlayerSetStorageValue) should (or have to be) updated to fit 1.x coding style
you can find the updated main function arguments in the sources on github
https://github.com/otland/forgottenserver
just find the source file and search for the function you're wanting to update
use this function document and search around for the 1.x function that you want/need to convert to
https://otland.net/threads/tfs-1-0-1-2-lua-functions.197202
(doPlayerSetStorageValue(cid, key, value) -> player:setStorageValue(key, value))
you should use the data folder from tfs github and transfer your scripts into the folder (much easier because some functions have been moved around into events folder)
you will also need to set up uniserver zero and use an aac (i recommend znote aac, here:
https://github.com/Znote/ZnoteAAC)
to install this:
open the www folder in the uniserver zero files and paste the files from znote aac into there
open uniserver zero and click Start MySQL and Start Apache
get a database schema from the github (it will be called schema.sql)
click phpMyAdmin in uniserver
create a new database and go to the import tab, and import the schema.sql that you have
follow the instructions for the znote tables (copy and go to the sql tab in phpMyAdmin, insert it then click run)
i might be wrong with the znote installation cause i don't remember much about it, tell me if you get any errors
