I don't think it does go in to suspension. If it was a reverse takeover or a change of significant business sector then they need to go through a relisting compliance that can take up to a month. Usually what happens there is a vote taken at an extraordinary meeting by shareholders to change the nature of the company's business. If the vote to change the business is approved the company's listing is then suspended until ASX re-compliance.

Because CCF's business is already in the agriculture sector, the addition of dairy business is within the same agriculture sector and so it does not require re-compliance and therefore should be just an administrative task to change the name and ticker code.

If you look on ASIC website, the ACN already names the company as Alterra Limited.
