please tell me how to transfer the database to another game, I tried using http code to transfer all the keys from the database, but I ran into problems writing that Instance

#2 
local DataStoreService = game:GetService("DataStoreService")
local LiveStats7 = DataStoreService:GetDataStore("LiveStats7")

local function printFirstKey()
    local success, iterator = pcall(function()
        return LiveStats7:ListKeysAsync()
    end)

    if success and iterator then
        local page = iterator:GetCurrentPage()
        if #page > 0 then
            local firstKey = page[1].Key
            print("key: " .. firstKey)
        else
            print("naah.")
        end
    else
        warn("nah.")
    end
end

printFirstKey()

Error:
19:24:39.063 Key is not a valid member of DataStoreKey “Instance” - Edit

#3

you cant transfer all players progress from project a to project b unless you use an external database

you can use print for debugging like this

print(page)

Use API keys, and make a system that when a player joins your new game, your API checks if that player already has data on the old game and writes that old game’s data to the new game.

#6

can you help me create an API?

#7

You’ll need a proxy, as HTTP service doesn’t allow requests to Roblox resources.

If you make an API key under the old game and give it universe.data-stores:read permissions, you can send a GET request to the endpoint https://apis.roblox.com/cloud/v2/universes/OLD_UNIVERSE_ID/data-stores/DATA_STORE_NAME/entries/key (no scope included; it doesn’t look like you used a scope) in order to get the data.

--this code is untested, and it might not work as I haven't used this API with HttpService before

local httpService = game:GetService("HttpService")

local apiKey = --api key, I would recommend using a secret and then HTTPService:GetSecret()

local function getData(player: Player)
    --you might want to retry multiple times, but I'll only show one here
    local success, response = pcall(httpService.RequestAsync, httpService, {
        --remember to use a proxy for the url, and to define the interpolated variables!
        ["Url"] = `https://apis.roblox.com/cloud/v2/universes/{old_universe_id}/data-stores/{data_store_name}/entries/{player.UserId}`, --remember to add key prefixes/suffixes
        ["Headers"] = {["x-api-key"] = apiKey},
        ["Method"] = "GET"
    })

    if (success) then response = httpService:JSONDecode(response) end

    if (not success or response.StatusCode ~= 200) then --failed
        --etc...
    end

    return response.value --the data
end
