I see that as per the MS SP Online limitations number of Terms in any Tenant cannot go beyond 200,000.
Managed metadata - 200,000 terms in Term Store, 1,000 global term sets, 1,000 groups
We have a scenario where we are migrating from some other content management system (Non SharePoint) to SP Online and we have 300,000 terms in the source system. Because of this limitation - we cannot migrate all the Terms.
Is there any work around (or) any other suggestion to handle this.
Thanks & Regards,
