# v1.4.3 Migration Guide

***

## Before

Previously, users would have to create 2 flows to perform upsert and query:

### Upsert

### Load Existing

With this technique, there are 2 drawbacks:

* Additional LLM call will need to be made in order for the upsert to happen
* Any slight changes will caused the flow to be upserted again

## After

Now, user can just use one node to accomplish all:

Users now have the option to manually kickoff the upsert by clicking the **green** button at the top right:

It comes with the new API - `/api/v1/vector/upsert`:

In future, we will be rolling out feature for querying, deleting indexes. This is the first step towards a more flexible way of performing vector-related operations. We strongly recommend users to update to the new nodes.
