SharePoint 2013-2019 migration: Using same service accounts from existing environment into migrated environment

We have a SP 2013 on-prem environment which we are migrating to SP 2019 on-prem environment. I understand we need to create new service accounts in new farm but can we use the same service accounts in SP2019 what we have in SP2013. Like the same farm account, app pool , search accounts etc. Eventually the SP2013 farm will be decommissioned after migration.
Is there any issue in doing that? Kindly explain.

Since this is Prod migration, we will keep the URLs same in SP2019 like we have in SP2013. We have a few Kerberos web-apps. Same service account will help to use the same SPN entry made earlier for such web-apps.

But please let me know if there are any consequences of using same service accounts.

Please note: We have 10 web applications which we are migrating over 5 weekends. 2 web-apps each weekend.

    Hello @shashank ,

    According to my research, if you are using the same domian, then you can use the same service account in SP2019 as in SP2013. That is, the domain used by SP2016 and SP2019 is the same as the domain of SP2013.

    We recommend that you make sure that SP2016 and SP2019 are connected to the DC in SP2013 before migrating.

    Thanks,
    Echo Du
