How to delete whole segments in the SDLTM and make the SDLTM as empty one?

Question

Hello All 
 
 I should create the new 48 SDLTMs based on the previous ones. 
 (I.e. I've already have 48 SDLTMs, but due to the some reasons, I need to create whole new 48 SDLTMs have same settings with the previous one.) 
 Of course, I can create them one by one, but it's too hard and I decided to copy the previous ones and delete whole TUs in copied ones. 
 In my guess, using the batch delete function would be a solution, but just would like to get any further advice from this forum. 
 Please let me hear your thoughts. 
 
 Thanks in advance.

 You might be able to simplify the too hard" part by creating the new ones on the basis of the old ones: 
 
 This way you'll get the same configuration as the old one without having to do all the settings manually. 
 But if that's also "too hard" then you could take the batch delete approach but frankly I think this will take you longer. 
 You could consider using a SQite tool such as DB Browser for SQLite and run this command: 
 DELETE FROM translation_units; 
 That will delete all records from the translation_units table. Also, remember to back up your data before running a DELETE command, as this operation is irreversible.... but instant! So a lot faster to get through.
