Hi there

Thanks for posting in the Lucidchart Community! The easiest way to maintain the position of your swimlanes and move the shapes within the swimlanes is to lock your swimlanes. To lock these shapes select only the swimlanes and click the 'Lock' icon in the toolbar at the top of the page. This will lock your swimlanes' size shape and position on the page. You can then select all other shapes on the page and move those shapes as necessary. 

I hope this helps! Let me know if you have any additional questions!

thank you this feature should be part of the swim lane help page! I have spent a lot of time moving shapes individually.
