I am in the same process of applying the maintanance pack. 
 
By going through the doco and TS , the maintainance order needs to be processed and will be available for the download, 
 
Although I cant find the very specific steps to apply the same. Shall dig through all the admin guides ,
 
At the very least run the DM to update the software and redeploy all the web applicaitons will be involved. 
 
Best ,
