You will need the Limited Write Contributions permission to move transactions between batches. With more than one organization, gifts can only move to a batch in the same organization.
You can move transactions from one batch to another, as long as both batches are manual batches and both are open. Auto-generated batches, which hold gifts processed online, cannot be used.
Warning: You cannot move a transaction into or out of a batch with a status of Closed. Reopen the batch first if you need to.
Moving transactions from a batch
Click Contributions > Batches in the left-hand menu. Find the batch you want to move the transactions to, and note its ID number.
Open the batch that holds the transactions, and tick the ones you want to move.
Click Bulk Actions > Move to another batch.
In the window that opens, enter the ID number of the destination batch.
Tick Navigate to batch after move? to open the destination batch afterwards, or leave it unticked to stay where you are.
Click Move.
Moving between organizations
If your account has two or more organizations, each batch belongs to exactly one organization, and so does every gift. A gift belongs to its organization for good.
Moving gifts to a batch in another organization is refused. There is no override and no confirmation to accept. It cannot be done.
Moving a whole batch to campuses of another organization is refused if its gifts belong to a different organization.
Automatic batches never collect gifts from two organizations.
A batch's merchant account and default designation must belong to the same organization as the batch.
Tip: There is no transfer between organizations. If money belongs in another organization, record it there as its own gift, in a batch that belongs to that organization. Each organization records its own side in its own books. What is an organization? explains how organizations keep their money apart.
