Intend changes to be preserved (6)
I believe the answer is:
tinned
'be preserved' is the definition.
('tinned' can be similar in meaning to 'preserved')
'intend changes' is the wordplay.
'changes' indicates anagramming the letters.
'intend' with letters rearranged gives 'TINNED'.
'to' acts as a link.
(Other definitions for tinned that I've seen before include "In cans" , "Canned" , "Sealed in a can" .)
