Hi Venkat Garikapati, the maintenance we are performing on AureaWorks (please note this only impacts https://community.jivesoftware.com/, not your own Jive site) is for maintenance only. We recently re-themed the community from JiveWorks to AureaWorks with a new design and layout. We are just adding some finishing touches, such as adding our Apps menu back to the top menu and making sure hyperlinks are blue instead of black so they are easily distinguishable. We are not making any major changes and everything has been tested successfully in UAT so there should not be any impact to you.
Hope this answers your questions!
Thanks for the confirmation.
