What happens to your LLCs after using a 1013 Exchange for a trade-up??

[Mohammed Milord]

Let's say you own three rental properties, and each property has its own LLC. What happens to the LLCs if you decide to trade the rental homes for an apartment building using a 1031 Exchange? Are the LLCs not under your control anymore or do you still have to dissolve them after the trade? Any clarification would be greatly appreciated.
