The delta migration is the final migration performed during your custom migration process. The aim of the delta migration is to ensure that all the data you have requested to be migrated is transferred and your target CRM is up to date right before the launch.
There are two options for your delta migration:
- Option #1: All new records created in the source CRM after the full migration is performed are migrated to the target CRM.
- Option #2: All new records created in the source CRM after the full migration is performed are migrated to the target CRM and the records migrated in terms of the full migration are updated in the target CRM.
Either option can be performed with no additional charges according to your preferences.
However, it should be noted that while Option #2 is considerably more thorough than Option #1, in the following instances, it may be best for you to opt for Option #1 (new records only):
- If the objects you have requested to be migrated are not often used or updated.
- If the record counts of the objects you have requested to be migrated are very high (on average 1 million+, but the max count depends on your CRM’s peculiarities and API limits). Keep in mind, that a delta migration using option #2 may take the same time to complete as the full migration time.
In short, the delta migration option you choose will not affect the price of your custom migration, however, it may change the timeline of your migration project. If you are not sure which delta migration option is best for your project, feel free to ask your account manager to advise you on the best option for you.
Note: Please inform your account manager about your delta migration preferences as early as possible in the project timeline in order to avoid complications such as project delay and/or additional charges during your migration process.
