My simple datastore isn't saving stats, should I migrate to datastore2?

How hard would it be to turn this into datastore2? This script worked fine and now it doesnt..

local DataStore = game:GetService("DataStoreService")
local MaxHealth1 = DataStore:GetDataStore("MaxHealth001")
local Level1 = DataStore:GetDataStore("Level001")
local Qalium1 = DataStore:GetDataStore("Qalium001")
local XP1 = DataStore:GetDataStore("XP001")
local HealthP1 = DataStore:GetDataStore("Health001")
local SwordP1 = DataStore:GetDataStore("Sword001")
local MeleeP1 = DataStore:GetDataStore("Melee001")
local ClassP1 = DataStore:GetDataStore("Class001")
local Points1 = DataStore:GetDataStore("Points001")
local Sign1 = DataStore:GetDataStore("Sign001")
local Tries1 = DataStore:GetDataStore("Tries001")
local Element1 = DataStore:GetDataStore("Element001")

Hell yeah! It sets itself up for garbage collection, it has caching, and it has a backup datastore so it prevents data loss.

Buuuut just like jasmin said there is no reason to make a separate datastore for each thing, you just have to make a table
