Long story.
The company I work for(MC) had a sister company(SC A) that hosted CRM for one of our other sister companies(SC B).
We sold SC A, and SC B was going to lose access to MSCRM. So MC migrated MSCRM to MC's infrastructure. We upgraded the whole thing since the CRM on SC A was ancient. Coworker was put in charge of migrating the data in which he had no idea or previous experience on CRM. So he exported the data as XML, and reimported it. All was fine and dandy until we realized it had removed the owner of the contacts in the data, and put him as owner.
We managed to find the original data. Problem is, a lot of the contacts in the data are no longer relevant. So my coworker had each sales person go through and mark the contacts in an excel sheet of which ones he wanted to keep. There were roughly 5k contacts per sales person, and the average salesperson only wanted to keep about 450. The remaining contacts were to be changed owner to the VP of Sales.
So what he did is he took the excel spreadsheet, and matched it with the exported XML file. Marked which ones were to keep the original owner, and changed the owner with Find and Replace tool of the remaining to the VP of sales. He never finished this project and left the company, and I got stuck with it. So here comes the questions and problem:
Problem: I changed the owner in the XML file for the remaining contacts to the VP of Sales. When I go to re-import the data, it had about 1200 successes, over 3k partial imports, and 1 error. I re-evaluated the data, found that the partial imports didn't change owner. Went back through the data, and made the proper changes. Re-import and there were 0 successes, over 3k partial imports, no errors. The data still didn't change owners. I found I can manually change it in the web interface, but only a max of 50 records at a time, because I have to pull up each salesperson, and sift through each page of 50 records, select the ones to change, and change.
Question 1: Is there a more efficient way to go through an entire list of over 3k contacts per sales person to change the owner?
Question 2: I would like to block any person from making changes to ownership of a contact besides those in the System Administration security group, which setting is this?
Question 3: Is there an easy way to find all users in a security group? Instead of clicking each user and going to manage roles.
Any advice would be extremely helpful.
