can i get my old textures from xbox 360 on minecraft if i have bedrock edition?

Some texture packs was not transfered from 360 edition to the newer Bedrock edition.

So I think this page lays out what you need.

The problem is that you can't transfer a world directly from Xbox 360 Minecraft to the latest Bedrock edition of Minecraft. You need to transfer it through the Minecraft: Xbox One edition first.

The
details are laid out here

Basically you'll go from Minecraft: 360 Edition > Minecraft: Xbox One Edition > Minecraft (bedrock)

Let us know if you have problems or questions.

Minecraft saves are backed up on both the Cloud and on the console. Unfortunately if you the saved world has already been deleted from the old Xbox, there's no way of getting the worlds back. I suffered it when transferring my Xbox One Edition worlds to
Bedrock edition, unfortunately nothing can be done.

From the sound of it, you have Minecraft Xbox One Edition. This edition of the game was discontinued a few years ago. It can still be played, but is no longer supported or updated. To get the bedrock version of the game, then you will have to purchase
Minecraft bedrock version from the Microsoft store on the Xbox. This version is just named Minecraft.

Download a texture pack (also known as a resource pack) in a compatible format such as .mcpack or .zip from a trusted source. Make sure the pack is designed for Minecraft Bedrock Edition.

Open the downloaded texture pack file. It should automatically open with Minecraft Bedrock if you have the game installed.

Minecraft Bedrock will import the texture pack and prompt you to apply it. Click the "Apply" or "Activate" button to enable the texture pack.

If the texture pack doesn't automatically open with Minecraft, you can manually import it. Copy or move the downloaded .mcpack or .zip file to the following location on your mobile device:

Android: Internal Storage/games/com.mojang/resource_packs

iOS: On iOS devices, the process requires a file management app like Documents by Readdle or iExplorer. Move the texture pack file to the "games/com.mojang/resource_packs" directory.

After moving the file, open Minecraft Bedrock and go to "Settings" > "Global Resources."

In the "My Packs" section, you should see the imported texture pack listed. Tap on it to activate it.
