We want to move all the data under Adobe to new Salesforce instance.

We are using Adobe sign, currently in production and getting used by sales and marketing team. We are upgrading Salesforce and moving to new Salesforce instance, wherein we will be installing Adobe sign also. When we will start using new instance, we will like to move agreements from existing instance to new instance. We want to move all the data under Adobe to new Salesforce instance. Can we get your support in this migration? We need your support in this activity.

We will be migrating data for other standard and custom objects also, which will take time, so we need to use same Adobe account on 2 instances, existing and new instance. Once new instance is fully ready, we will suspend existing instance. We will like to understand, rather confirmation from you whether we can use same account in multiple instances and no issue as such in this scenario.
