I am currently working on the draft version of "Maintenance Review and maintenance process for exisiting sites: Update, Consolidate, Incorporate; Remove: Transfer." I wanted to share my interpretation of the following to make sure we are all on the same page. 
Update: ensuring the accuracy and timeliness of the information presented; regularly updating and keeping published information cuurrent.
Consolidate: joining together two or more webpages that may contain the same inforation
Incorporate: to unite or work special projects into something already existent so as to form an indistinguishable whole
Remove: delete or incapacitate obsolete web pages/sites
Transfer: to move or shift the control of a web page/site
Please let me know what you think. Thanks!!
