# `bigdl-llm` Migration Guide
 | 
						|
 | 
						|
This guide helps you migrate your `bigdl-llm` application to use `ipex-llm`.
 | 
						|
 | 
						|
## Upgrade `bigdl-llm` package to `ipex-llm`
 | 
						|
 | 
						|
> [!NOTE]
 | 
						|
> This step assumes you have already installed `bigdl-llm`.
 | 
						|
 | 
						|
You need to uninstall `bigdl-llm` and install `ipex-llm`With your `bigdl-llm` conda environment activated, execute the following command according to your device type and location:
 | 
						|
 | 
						|
### For CPU
 | 
						|
 | 
						|
```bash
 | 
						|
pip uninstall -y bigdl-llm
 | 
						|
pip install --pre --upgrade ipex-llm[all] # for cpu
 | 
						|
```
 | 
						|
 | 
						|
### For GPU
 | 
						|
Choose either US or CN website for `extra-index-url`:
 | 
						|
 | 
						|
- For **US**:
 | 
						|
 | 
						|
  ```bash
 | 
						|
  pip uninstall -y bigdl-llm
 | 
						|
  pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/
 | 
						|
  ```
 | 
						|
 | 
						|
- For **CN**:
 | 
						|
 | 
						|
  ```bash
 | 
						|
  pip uninstall -y bigdl-llm
 | 
						|
  pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/cn/
 | 
						|
  ```
 | 
						|
 | 
						|
## Migrate `bigdl-llm` code to `ipex-llm`
 | 
						|
There are two options to migrate `bigdl-llm` code to `ipex-llm`.
 | 
						|
 | 
						|
### 1. Upgrade `bigdl-llm` code to `ipex-llm`
 | 
						|
To upgrade `bigdl-llm` code to `ipex-llm`, simply replace all `bigdl.llm` with `ipex_llm`:
 | 
						|
 | 
						|
```python
 | 
						|
#from bigdl.llm.transformers import AutoModelForCausalLM # Original line
 | 
						|
from ipex_llm.transformers import AutoModelForCausalLM #Updated line
 | 
						|
model = AutoModelForCausalLM.from_pretrained(model_path,
 | 
						|
                                             load_in_4bit=True,
 | 
						|
                                             trust_remote_code=True)
 | 
						|
```
 | 
						|
 | 
						|
### 2. Run `bigdl-llm` code in compatible mode (experimental)
 | 
						|
To run in the compatible mode, simply add `import ipex_llm` at the beginning of the existing `bigdl-llm` code:
 | 
						|
 | 
						|
```python
 | 
						|
import ipex_llm # Add this line before any bigdl.llm imports
 | 
						|
from bigdl.llm.transformers import AutoModelForCausalLM
 | 
						|
model = AutoModelForCausalLM.from_pretrained(model_path,
 | 
						|
                                             load_in_4bit=True,
 | 
						|
                                             trust_remote_code=True)
 | 
						|
```
