Dear Friends I am new to Koha. We are running koha in or organization. Somebody in our organization, setup koha and it is working since then. I am assigned a task in koha. I have seen tables in koha database little bit. In branches table, It has 8 branches records.. Out of these 8 records, Two Branches are going to merge. For Example. branchcode=AA branchcode=AB Now I have to make these two branches in to one branch with branchcode A but this branchcode has many relationships in other tables. What is the right way of doing it. What I understand is that, First I change the values in all tables where branch code is there like AA should be changed to A and AB should be changed to A Then finally I change either AA or AB in branch table., to A, and delete one row which I don't change. Then Will it work? In OPAC, there are some report/search, in that some statistics come So that report should also be change. I think this will change, it values in tables will be changes. Please suggest. Thanks for help. Manoj
