This is a guide for the migration of subgraphs from the Hosted Service (also known as the Hosted Service) to The Graph Network. The migration to The Graph Network has been successful for projects like Opyn, UMA, mStable, Audius, PoolTogether, Livepeer, RAI, Enzyme, DODO, Opyn, Pickle, and BadgerDAO all of which are relying on data served by Indexers on the network. There are now over 200 subgraphs live on The Graph Network, generating query fees and actively indexing web3 data.

This will tell you everything you need to know about how to migrate to the decentralized network and manage your subgraphs moving forward. The process is quick and your subgraphs will forever benefit from the reliability and performance that you can only get on The Graph Network.

Feel free to leverage the [#Curators channel](https://discord.gg/rC8rBuRtbH) on Discord to let Curators know that your subgraph is ready to be signaled. It would also be helpful if you share your expected query volume with them. Therefore, they can estimate how much GRT they should signal on your subgraph.

### Upgrading a Subgraph on the Network

If you would like to upgrade an existing subgraph on the network, you can do this by deploying a new version of your subgraph to the Subgraph Studio using the Graph CLI.
An upgrade requires GRT to be migrated from the old version of the subgraph to the new version. This means that for every upgrade, a new bonding curve will be created (more on bonding curves [here](/curating#bonding-curve-101)).
84

The new bonding curve charges the 2.5% curation tax on all GRT being migrated to the new version. The owner must pay 50% of this, or 1.25%. The other 1.25% is absorbed by all the curators as a fee. This incentive design is in place to prevent an owner of a subgraph from being able to drain all their curator's funds with recursive upgrade calls. The example below is only the case if your subgraph is being actively curated on. If there is no curation activity, you will have to pay a minimum of 100 GRT in order to signal yourself on your own subgraph.

- 100,000 GRT is signaled using auto-migrate on v1 of a subgraph

- Owner upgrades to v2. 100,000 GRT is migrated to a new bonding curve, where 97,500 GRT get put into the new curve and 2,500 GRT is burned
89
-
- The owner then has 1250 GRT burned to pay for half the fee. The owner must have this in their wallet before the upgrade, otherwise the upgrade will not succeed. This happens in the same transaction as the upgrade.

### Maintaining a Stable Version of a Subgraph

If you're making a lot of changes to your subgraph, it is not a good idea to continually upgrade it and front the upgrade costs. Maintaining a stable and consistent version of your subgraph is critical, not only from the cost perspective, but also so that Indexers can feel confident in their syncing times. Indexers should be flagged when you plan for an upgrade so that Indexer syncing times do not get impacted. Feel free to leverage the [#Indexers channel](https://discord.gg/8tgJ7rKW) on Discord to let Indexers know when you're versioning your subgraphs.

Subgraphs are open API that external developers are leveraging. Open APIs need to follow strict standards so that they do not break external developers' applications. In The Graph Network, a subgraph developer must consider Indexers and how long it takes them to sync a new subgraph **as well as** other developers who are using their subgraphs.

You can update the metadata of your subgraphs without having to publish a new version. The metadata includes the subgraph name, image, description, website URL, source code URL, and categories. Developers can do this by updating their subgraph details in the Subgraph Studio where you can edit all applicable fields.

While you get to decide on your query budget, there is no guarantee that an Indexer will be willing to serve queries at that price. If a Gateway can match you to an Indexer willing to serve a query at, or lower than, the price you are willing to pay, you will pay the delta/difference of your budget **and** their price. As a consequence of that, a lower query price reduces the pool of Indexers available to you, which may affect the quality of service you receive. It's beneficial to have high query fees, as that may attract curation and bigname Indexers to your subgraph.

Remember that it's a dynamic and growing market, but how you interact with it is in your control. There is no maximum or minimum price specified in the protocol or in the Gateways. For example, you can look at the price paid by a few of the dapps on the network (on a perweek basis), below. See the last column which shows query fees in GRT. For example, [Pickle Finance](https://www.pickle.finance/) has 8 requests per second and paid 2.4 GRT for one week.
