I suggest you go to the "Contact Us" page of the Incline Software website. They are the makers of Ancestral Quest. https://www.ancquest.com/contacts.htm
Ask them for help with getting started. They will need to know what version of AQ you use.
All depending on WHAT "Version" of "Ancestral Quest" you are using ...
[ I believe that the current Version is: 16 ]
And, WHAT Computer, "Operating System"; and, "Browser", you are using ...
[ Plus, are they up-to-date, latest versions - or, very OLD versions ]
Some of the OLD, Computers; and, versions of the "Operating Systems"; and, "Browsers"; plus, a very OLD version of "Ancestral Quest", might not work well together with the current version of "Family Tree" of 'FamilySearch'
And, as far as what the current version (16) of "Ancestral Quest" requires ...
Ancestral Quest System Requirements:
[ for "Windows" version; or, "Mac" version ]
That said ...
Directly from the Website of "Ancestral Quest":
▬ Features to Connect Your Data with FamilySearch.org
Depending on all of the aforementioned, technically, you should be able to "Compare" what you have in your (personal) "Ancestral Quest" Database; and, add any individual/person from your Database NOT already in "Family Tree" of 'FamilySearch; plus, for those individuals/persons already in "Family Tree" of 'FamilySearch', you should be able to add anything (eg. Details / Documents / Photographs / etc) from your Database that is NOT already in "Family Tree" of 'FamilySearch'.
As an aside ...
Just in case you have NOT used "Family Tree" of 'FamilySearch' before; and, are NOT aware of the basic intents and premise of "Family Tree" of 'FamilySearch' ...
Apologies if you are already aware of all this; but, just in case ...
We do not have our OWN "Tree" in "Family Tree" of 'FamilySearch'.
We ONLY have "Branches" (ie. "Ancestral" lines), that are interconnected, in this SINGLE "One" World "Tree", for all of us, that is "Family Tree" of 'FamilySearch'.
"Family Tree" of 'FamilySearch' is NOT like 'On-Line' "Websites" (eg. "Ancestry_com"; or "MyHeritage_com"; or, the like); and/or, 'standalone' personal (computer) programmes (eg, the OLD, now no longer supported, "PAF"; or, "Ancestral Quest"; or, the like).
We DO NOT have "Private"/"Personal" 'Trees' in "Family Tree" of 'FamilySearch' like other 'On-Line' "Websites"; and/or, 'standalone' personal (computer) programmes.
We do not even, own; or, manage; and, are NOT even responsible for, the "Deceased" individuals/persons in "Family Tree" of 'FamilySearch'.
"Family Tree" of 'FamilySearch' is built on a "Open Edit" Platform - hence, why any registered User/Patron can "Edit" (ie. Add, Delete; and/or, Change) ANY "Deceased" individual/person in "Family Tree" of 'FamilySearch'.
You can ONLY see "Deceased" individuals/persons in "Family Tree" of 'FamilySearch', regardless of who the User/Patron was that initially created those "Deceased" individuals/persons; as, they DO NOT reside with the User/Patron who initially created them - they are "Public".
There is an except, that being with this 'rider', that you can ALSO only see "Living" individual/person in "Family Tree" of 'FamilySearch' that YOU created; as, they reside in your "Private Spaces".
No other User/Patron can see ANY "Living" individuals/persons that were created by another User/Patron; as, they ONLY reside in the "Private Spaces" of the User/Patron who created them.
Here is a good place to start, with how things work in "Family Tree" of 'FamilySearch' (and, other programmes as well):

Incline Software Releases Ancestral Quest 16
You will need the latest release of version 16. If you have paid for an earlier release, you can still use 16 basic. FS keeps making changes to their API so earlier versions will not be able to talk to properly with FS.
Also, note that in general NOBODY can "put their Family Tree on Family Search". This is because there is only ONE modifiable tree there and that is the FamilySearch FamilyTree. Although it is owned by FamilySearch, anyone can contribute and modify it. It is a single shared tree for the world, currently containing around 1.3 Billion names in it. Nobody has there own privately controlled trees there. However, you will likely discover that as much as 70%-90% of your current tree is ALREADY in the FamilySearch FamilyTree.
You can use your AQ tree data to verify and improve upon the records already in the FamilySearch FamilyTree if your records are more accurate and have better reasoning documented with them than those already in the FSFT.
Basically, what you can do is first create your own person record from your FS account. Then if your parents are still alive, add them as parent records for your own record. Repeat this until you have all living ancestors recorded in your FS account. Since these records are all of living individuals, only you will be able to view and modify them. For privacy reasons, no one else can see them.
Now using your AQ database, go in and LINK each of those living ancestors from your AQ database to those new records that you have created in the FamilySearch FamilyTree. Again note that because those records are for living persons, they are in your Private Space. That part of the FSFT is only visible to you.
Now you will start linking in all of your AQ database DECEASED records to the equivalents that are in the FSFT. in FSFT go to one of the last living relatives that you have entered there and add a parent. You can perform a search of the FSFT to find that parent if it is already there. If you can't find anything at all in the FSFT, then add a new record in the FSFT and link it to the equivalent record in your AQ database. Then move up your tree to unlinked records and repeat with the FSFT.
Note that this procedure can be accomplished in more than one way. For example AQ v16 allows you to search for these parent records that might be in the FSFT based on all the data that you have already recorded in your AQ database for those individuals. Furthermore, after you have linked a record in your AQ database to one in the FSFT, you can transfer data from that record in AQ to the one in the FSFT using the comparison function in AQ which allows you to see all of the data for a record in your AQ DB side by side with all of the data for the linked record in the FSFT.
Lastly, since a good number of your person records in the AQ database WILL match up with equivalents in the FSFT, be very careful about overwriting pre-existing and well documented vitals already in the FSFT. Since the FSFT is shared, those data and other vitals may have years of research and documentation attached to them.
Until you get a good feel on doing this, it may be helpful to have both a window with AQ running as well as a window where you've logged into FS and viewing records in the FSFT both running at the same time.
Beware of anyone suggesting that you use the FS GEDCOM Compare tool for uploading data via a GEDCOM file. When you already have an AQ database, it is far better to just LINK and then sync data directly between AQ and the FSFT. Besides, the GEDCOM Compare tool has some serious shortcomings that can hide damage you are doing to the shared tree. Furthermore, it doesn't allow you to upload sources that you have documented in AQ directly to the associated records in the FSFT. You need to go straight through the API (i.e., without using a GEDCOM file) in order to do that.
In closing, if you have not seen any of the training videos that Incline Software has on their website, you should really have a look. They have several on dealing specifically with interfacing with FamilySearch in different subjects such as I have just talked about.
Good luck with that!
