Combining geodatabases

[JerryClark2]

How would I go about combining my custom geology gdb with the new gems gdb. I have a project where I have had the new gems gdb but it does not have all the same domains and dropdowns i use. So I am trying to merge the to together. Can someone give me some direction on the.

Have you tried to "copy/paste" feature dataset/feature class using Arccatalog or ArcGIS Pro from one geodatabse to another geodatabase.

If the above suggestion did not work, then please provide more information as per below:

1.  Geodatabse version 

2. DBMS and it's version where geodatabse created

3. How many feature classes and tables present. or How big the geodatabse is.

4. Is there any complex feature like, geometric network, topology etc.

5. Do you have attachment feature classes

6. Why you want to merge 2 geodatabase. What you want to accomplish by merging 2 gdb.

Thanks,
