i think that the solution is to after this script delete a attachment on issue and add a post function at last transaction in the sub-task where copy attachment on issue and after delete on sub-task

Code to create Sub-task with a single attachment:

//Code make by Henning Tietgens
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import org.apache.log4j.Logger

final SUBTASK_ISSUETYPE_NAME = "Sub-task"

if (issue.issueType.name != SUBTASK_ISSUETYPE_NAME) {
def issueFactory = ComponentAccessor.issueFactory
    def constantsManager = ComponentAccessor.constantsManager
    def issueManager = ComponentAccessor.issueManager
    def subTaskManager = ComponentAccessor.subTaskManager
    def attachmentManager = ComponentAccessor.attachmentManager

def currentUser = ComponentAccessor.jiraAuthenticationContext.loggedInUser
def subTaskId = constantsManager.allIssueTypeObjects.find{it.name == SUBTASK_ISSUETYPE_NAME}.id

issue.attachments.eachWithIndex{att, i ->

def newSubTask = issueFactory.getIssue()
        newSubTask.setSummary("Sub-Task Attachment: " + (i + 1))
        newSubTask.setDescription("Sub-Task with an Attachment")
        newSubTask.setParentObject(issue)
        newSubTask.setReporterId(currentUser.username)
        newSubTask.setProjectObject(issue.projectObject)
        newSubTask.setIssueTypeId(subTaskId)

issueManager.createIssueObject(currentUser, newSubTask)
subTaskManager.createSubTaskIssueLink(issue, newSubTask, currentUser)

attachmentManager.copyAttachment(att, att.authorObject, newSubTask.key)
    }
}

After Second POST-Fucntion to delete every Attachment in the main issue:

//
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.AttachmentManager

AttachmentManager attachmentManager = ComponentAccessor.attachmentManager

def attachments = attachmentManager.getAttachments(issue)
attachments.each {attachment ->;
    attachmentManager.deleteAttachment(attachment)
}

And this code is for sub-task Transaction(POST_Function): this script copy Attahcment on the main after delete every attachment in this sub-task

//Code make by Henning Tietgens

import com.atlassian.jira.component.ComponentAccessor

final SUBTASK_ISSUETYPE_NAME = "Sub-task"

if (issue.issueType.name == SUBTASK_ISSUETYPE_NAME) {
    def attachmentManager = ComponentAccessor.attachmentManager
    issue.attachments.each{att ->
        attachmentManager.copyAttachment(att, att.authorObject, issue.parentObject.key)
        attachmentManager.deleteAttachment(att)
    }
}

ok
