# What happens if I delete a units base rate?

## Importance of Base Rates in Aloha for OTA Connections

It is crucial to remember that **base rates are the foundation of all connections or mappings between Aloha and OTAs** (Booking, Expedia, Airbnb, etc.). Without a specific base rate for an OTA, no smart rules will be applied or reflected on the connected platform.

Here are the necessary steps to create a new base rate and, if needed, safely remove the old one.

## Steps to Change a Base Rate

1. **Create the New Base Rate**

* First, create the new base rate in Aloha by going to the Base Rates section in the Prices Tab, click Add Base Rate and complete the pop up box accordingly.

2. **Check the Mapping of the Old base rate**

* Before deleting the old base rate in Aloha, it is essential to verify that it is **not mapped to any channel** in the channel manager.
* Go to the **Actions** menu in the existing rate plan and select **Edit**.

3. **Remove the Old base rate’s Mapping**

4. **Connect the new base rate**

* Finally, associate the new base rate with the desired channel, ensuring that all details are correctly configured and ready to be reflected on the OTAs.
