-Dear biomed user,+Dear Biomed users,
-You have <text type="​danger">​XXX</​text> ​files on SE <text type="danger">YYY</​text>​ which will be decommissioned ​by <text type="​danger">​X</​text>​.+we've received notice that the SE <text type="​danger">​SEName</​text> ​(hosted by site <text type="siteName">SSS</​text>​), which is used by Biomed, ​will be decommissioned ​on <text type="​danger">​date</​text>​. ​
-We have to move these files away or remove all the corresponding entries from the LFC (using lcg-ra ​<guid> <lfn>)  in case you no longer need the data. Please don't hesitate to contact us (biomed-technical-support [AT] googlegroups [DOT] com) in case you have any questions or if you experience difficulties in this process.+This is tracked through ​the following ticket: 
 +<text type="​danger"​>GGUS link</text>
-The list of the corresponding ​files is attached/available <text type="​danger">​HERE</​text>​+If you have files on this SE, please consider checking quickly whether they have replicas somewhere else, or whether you should get/replicate them to avoid any data loss.
-Also, note that it is **not** recommended to try to move many files in parallel: due to scalability issues of the SE, only a limited number ​of concurrent connections can be initiated.+You can find relevant LFNs using 
 +dirac-dms-find-lfns --SE=[SE name] Path=/ 
 +dirac-dms-replica-metadata fileContainingLFNs SE 
 +should return available replicas ​of individual files. 
 +Kind Regards 
 +<text type="​danger">​Name</​text>​ for Biomed support
-Thanks in advance,\\ 
-The biomed technical team on shift.
