Hi @UserZ , unfortunately yes, I’ve seen this happen a few times, and your frustration is completely justified.
The short and painful truth is that legacy quote templates cannot be re-enabled once a portal is force-migrated to the new Quotes tool.
Deleting new-style templates does not restore access to legacy quotes, because the migration is account-level, not template-level. Once HubSpot flips that switch, the legacy quote editor is effectively retired for that portal.
What sometimes helps, depending on timing, is checking whether HubSpot Support can temporarily roll the portal back if the migration was very recent and not fully completed. This is rare and time-sensitive, and Support will usually escalate it internally if it’s even possible. If they haven’t already, ask explicitly whether a rollback to legacy quotes is technically still an option, not just whether legacy templates can be reused.
If rollback is not possible, the only supported path is to rebuild the template in the new quote system, using custom modules and CSS. The good news is that the new quote editor is more flexible long-term, but the bad news is that legacy HTML cannot be imported 1:1. HubSpot documents this limitation pretty clearly now, though it’s easy to miss until you hit it (Manage quotes )
One practical workaround I’ve seen teams use is to extract the legacy HTML and CSS you built and reuse chunks of styling logic inside custom quote modules, instead of starting from zero conceptually. It’s still work, but it saves design thinking time even if it doesn’t save build time.
If this migration blocked an active rollout, I would also strongly recommend posting this in the Ideas forum or pushing Support to log it as feedback. HubSpot has been tracking quote migration friction closely, especially for RevOps-heavy portals (https://community.hubspot.com/t5/HubSpot-Ideas/idb-p/HubSpot_Ideas )
hopefully this gives you clarity instead of more ambiguity.
