You may find that some DNS records do not resolve during an account transfer.
This can occur if the transferred domain's DNS is hosted in a DNS cluster which the destination server syncs to. This is because when the account is created on the destination server the DNS zone will be sync'd to the cluster, then later when the DNS zone is restored, it will be synced again
There is no workaround for this, but the records should reappear quickly. More information regarding transfers can be found in our documentation.
