Centennial Campaigns...how to separate and best practices

Hi friends!  


We will be starting to fund raise for our centennial campaign very soon, and figured I'd ask this great community about the best practices you've learned when setting up centennial campaigns!  Is it best to create it's own campaign?  For multi year pledges/ gifts, is it best to create separate pledges for each year or one pledge with payments each year?

Any advice/ recommendations is appreciated! Thanks in advance!
