merging duplicate tickets of same issue type

[Thrisha]

I have 3 different projects and 'n' number of issue types in it

In that 'n' number of issue types (let's assume issue types n1, n2, n3...)  I need to merge the duplicate tickets - ticket 1 and ticket2 of issue type n1 with following conditions. 

i) it should restrict issue types- merging tickets belonging to same issue type 

ii)it should allow to merge custom fields also

iii) it should get merged in either ticket 1 or 2 and not in a new ticket 

iv)this should support all types of custom field to merge (text, single/multi select, labels)

I tried Issue merge for jira, ticket merger, duplicate AI- it has certain limitation

Can anyone suggest a plugin for merging duplicate issues

Requirement: If a n1 has duplicate ticket 1, migrate the duplicate ticket 1to a master n1 ticket 2, or ensure reporting rolls up the info of all duplicates
