Is it possible to transfer Data to the ProfileService without rollbacking everyone else data to the zero?
Legacy Script
local dataStoreService = game:GetService("DataStoreService")
local dataStore = dataStoreService:GetDataStore("PlayerStatistics")
ProfileService Script
local ProfileStore = ProfileService.GetProfileStore("PlayerStatistics", Template)
As you can see i’m using the same DataName (and the same player.UserId as the key in a function), so, how would i make to transfer everyone progress to the new system?
Hello, I had a similar problem today. I know I came late to the party, but this is how I did it:
Say you have an old DataStorage called PlayerData and you have decided to use ProfileService instead of your old method. What I did is I made a new DataStorage and called it PlayerDataV2 and made ProfileService use that one. Then in the DataTemplate of ProfileService, that you pass in ProfileService.GetProfileStore(), I have added a key called “DidDataTransfer” and set that equal to false. So whenever a player joins and has their profile loaded I would check if profile.Data.DidDataTransfer == false. If true, then get your old datastore and see if they have data in that datastore, then just transfer it to profile.Data.
local function OnPlayerAdded(player: Player)
local profile = ProfileStore:LoadProfileAsync("Player_" .. player.UserId)
if profile ~= nil then
profile:AddUserId(player.UserId)
profile:Reconcile()
profile:ListenToRelease(function()
Profiles[player] = nil
player:Kick()
end)
if player:IsDescendantOf(Players) == true then
Profiles[player] = profile
else
profile:Release()
end
else
player:Kick("Data couldn't be loaded. Try again later.")
return
end
local data = profile.Data
if not data.DidDataTransfer then
local oldData = game:GetService("DataStoreService"):GetDataStore("Players"):GetAsync("Player_" .. player.UserId)
if oldData then
for i,v in oldData do
profile.Data[i] = v
end
end
data.DidDataTransfer = true
end
end
Make sure to replace “PlayerStatistics” with the appropriate name for your data store and profile store. Also, ensure that the placeholders (-- Value for ... ) in the transferData function are replaced with the actual values fetched from the legacy DataStore for each player.
This script should fetch data from the legacy DataStore for each player and transfer it to the ProfileService without affecting other players’ data.
Summary
local dataStoreService = game:GetService("DataStoreService")
local legacyDataStore = dataStoreService:GetDataStore("PlayerStatistics")
local ProfileService = require(game.ServerScriptService:WaitForChild("ProfileService"))
local ProfileStore = ProfileService.GetProfileStore("PlayerStatistics", Template)
local function fetchData(player)
local success, data = pcall(function()
return legacyDataStore:GetAsync(tostring(player.UserId))
end)
if success then
return data or {} -- Return the data or an empty table if it doesn't exist
else
warn("Failed to fetch data for player " .. player.Name .. ": " .. data)
return {} -- Return an empty table in case of an error
end
end
local function transferData(player)
local profile = ProfileStore:LoadProfileAsync(tostring(player.UserId))
if profile then
local data = fetchData(player)
profile.Data = {
Agility = data.Agility or 0,
Attack = data.Attack or 0,
BoostX1 = data.BoostX1 or 0,
BoostX2 = data.BoostX2 or 0,
CurrentQuest = data.CurrentQuest or "",
Defense = data.Defense or 0,
Dragon1 = data.Dragon1 or "",
Ki = data.Ki or 0,
LOCK = data.LOCK or false
}
profile:Save()
profile:Release()
end
end
for _, player in ipairs(game.Players:GetPlayers()) do
transferData(player)
end
