 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](/network/curating#bonding-curve-101)).
 
-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. If there is no curation activity, you will have to pay a minimum of 100 GRT in order to signal your own subgraph.
