Copy Imported date to Creaction date

Smart CRM & Sales Hub Account & Settings
1

Hello,

We have done a massive import from old CRM to Hubspot but Creation date of all objects was set to the migration date. We have date (e.g. in Proposals) with the Presentation field date that would be good to be used as Creation date. Is there a way to to a full copy from this field to creation one so this date could be used for reporting and statistics and not the “fake” creation date? We need do this also in Calls, Companies, etc…

Thanks

Hi @DFB,

No, this is, as far as I know, not possible. You can always create custom date fields but the defaul HubSpot Create date will store the time when the record was created in HubSpot. It cannot be edited.

Edit: The deal object is an exception to this. The deal create date can be edited. Edit a property value for a record

Best regards!

Hi @karstenkoehler,

Everybody said the creation date cannot be edited by I can edited it. See the changes logs of a business:

According the field/properties of the object, what is not editable is the field itself, not the value, I guess…

So, what I would like is to “copy” to this property, the value of the date of other custom field where I keep the “true” creation date of the object in our previous CRM.

Thanks

Hi @DFB

Is Proposals a custom object or what are you referring to.

I’m just in the process of doing preparing a large CRM import for a customer and was able to import historic deals with the correct create dates without a problem.

Have you actually imported and mapped the create date of objects?

If so did you get an error message?

If not, have you tried re-running the import an just matching and over-writing the create date?

Proposals are “business” (I guess in Hubspot).

We have imported via API the data. There’s no error related to my question.

Probably overwritting the objects could the Creation Date overwritted? Is this a proposal for trying or something that really works?

Hi @DFB

There is no “business” object in HubSpot. I’ll just assume you are talking about deals.

Yes, the create date can be changed. Like I said, I changed or set this via the initial import. I assume you can change this via API calls too, but have no experience on doing so myself.

I recommend testing it, by picking a few deals and either:

  • Match and import the actual create date from your old CRM, or
  • Try changing it via an API call

hi @franksteiner79 ,

I would expect if someone knows how to do this. I already know things to try and would like to do something already done, not tried.

Thanks

Hi @DFB

Two things I would recommend:

  1. Keep in mind this a community of volunteers.
  2. If you want clear and explicite guidance, you need to provide a clear and unambigious description of your current scenario, that includes things like:
    • screenshots,
    • a clear explanation of what you are trying to do,
    • where you are doing it,
    • which HubSpot objects are impacted,
    • what you have tried,
    • and what your expected/desired outcome is.

There are still a few gaps and uncertainties in the information you have provided.

If you are unable or unwilling to test the two options outlined by me to fix the issue, we are at an impass.

@DFB I understand you’re finding the import process quite frustrating. It’s important to know the difference between read-only properties and those you can modify. For instance, creation properties like the contact’s creation date and the company’s creation date are read-only. You can’t change them at all.

In contrast, in a deal, you can change the creation date. So, when you’re analysing this, you need to look at each object separately. For contacts and companies, it’s not possible to change the creation date as HubSpot sets it automatically. However, for deals, you might be able to modify it with the UI and even with Workflows or the APIs.

Hi @DFB

The short version: most HubSpot system properties like Create date are hard-locked and can’t be overwritten after import. That’s why you’re seeing everything stamped with the migration day. The one big exception is Deals, where the create date can indeed be updated via import or API if you map it explicitly

(Edit a property value for a record )

For Contacts, Companies, and Calls though, HubSpot treats the creation date as system history, not something you can change. The workaround I’ve seen succeed in 2024–2025 migrations is to:

  • create a custom property such as “Original CRM Creation Date”,
  • backfill that with your legacy date field,
  • then use that field in your reports and filters instead of the default system property. HubSpot supports full reporting off custom date fields

This way you preserve the “true” history without trying to rewrite HubSpot’s audit trail.

If your reporting spans multiple objects (calls, companies, deals, custom objects), the key is just to normalize that custom date property across each object type so you can align them in dashboards.

And since you mentioned doing this across several objects: some teams sidestep the heavy lifting by using a sync platform that can pull in legacy system dates and keep them aligned in HubSpot, even after the migration. Stacksync, for example, is often used that way it keeps historical timestamps consistent across CRMs and databases in real time, so you don’t get stuck with skewed reporting windows after a big import.

Hope this helps.
