# Python script to convert EBS Volume
2+
3+
Python script to convert EBS volume from gp2 to gp3 or from io1 to io2 and read input from csv file with a format volume_id,volume_type
4+
5+
## Usage
6+
7+
```python3 ebs_volume_conversion.py -h
8+
usage: ebs_volume_conversion.py [-h] [-f FILE] volume_id volume_type
9+
10+
positional arguments:
11+
volume_id The EBS volume id of the Volume to be convert
12+
volume_type The new EBS volume type to be converted gp3 or io2
13+
14+
optional arguments:
15+
-h, --help show this help message and exit
16+
-f FILE, --file FILE A csv file containing ebs volume id and volume type to convert
17+
```
18+
19+
# Example
20+
21+
1. To convert an ebs volume from gp2 to gp3
22+
23+
```
24+
python3 ebs_volume_conversion.py -volume_id <vol-id> -volume_type gp3
25+
```
26+
27+
2. To convert an ebs volume from io1 to io2
28+
```
29+
python3 ebs_volume_conversion.py -volume_id <vol-id> -volume_type io2
30+
```
31+
32+
3. You can pass a csv file containing ebs volume id and volume type to convert
33+
```
34+
python3 ebs_volume_conversion.py -f ebs_volume.csv
35+
```
