Request to merge duplicate MasterChef Croatia TV series listings

Hello IMDb Community,

I would like to request assistance with merging two IMDb listings that appear to represent the same Croatian television series, MasterChef Hrvatska.

The two listings are:

1. MasterChef Hrvatska (2011) – https://www.imdb.com/title/tt2409790/

2. MasterChef Croatia (Hrvatska) – https://www.imdb.com/title/tt15727336/

The series originally aired on Nova TV in 2011, 2012 and 2015. After a hiatus, it returned in 2021 with its fourth season and a new judging panel. The programme has continued through its ninth season in 2026.

The first IMDb listing mainly contains episodes from the first three seasons, while the second includes episodes and credits from later seasons.

I would like to consolidate these listings, preferably retaining tt15727336 as the main page.

However, I understand that IMDb does not allow two TV series to be merged directly when both already contain episode records.

Could an IMDb staff member please advise on the correct procedure for merging these listings while preserving the existing episodes, cast and crew credits, and ratings?

Thank you for your assistance.
