Data warehouse ETL - dropping all FK but what about extended properties? Do they need to be re-added

Question

So Im setting up a SSIS package to refill the DB, drop/re-add the keys etc and I notice that there are extended properties added in the definition of the keys added to the fact table.  Do these needed to be added back EXACTLY as they are defined (when
viewing them in management studio via right-click > script key) ?
Im thinking they do as they mention the DSV, so Im guessing that not adding them back might mess up the DSV?

Lightning is a problem for you because it hooks into Thunderbird at a low level and you need a version compiled for the platform Thunderbird is running on. So you can't do the preferred solution, which is to put your whole profile in a shared folder and have both instances of Thunderbird reference the same profile. (Ditto for Enigmail). Lightning may become an integral part of Thunderbird in an upcoming release, at which point this limitation due to Lightning should disappear.
And if you can't use a shared profile, you can't set your Lightning, or your Address Book, to share a common set of files. Put another way, the linkage from Thunderbird to its address book files and calendar data is hard-coded, and not exposed where we can adjust it. :-(
The halfway house is to place your mail stores in a shared place, and use the Local Directory setting in each account's settings to connect to it. They don't need to be in the profile; what's more important in your case is that they are in a folder accessible to both operating systems.
Look in your profile; everything under Mail and ImapMail needs to be moved out to a shared folder. Note the entries in Thunderbird under Local Directory before you do this, and reconstruct those pathnames in Thunderbird, but adjusted to suit their new locations.
(You can see here that you need to make many adjustments, one per account, in each instance of Thunderbird, so it's a high-maintenance solution and this is why we don't recommend it when the alternative, moving the whole profile, is possible.)
I share address books and calendars between Thunderbirds on various computers (and my phone and tablet) by syncing to something in the cloud; Google Contacts and Google Calendar are my choices, using gContactSync and CalDav.
Having made the break myself some years ago, I'd recommend you break away from Windows. ;-)
