Migrating Email
Last updated: July 18, 2025
This article will walk you through the process to migrate your support email from another support system to Pylon.
For a higher level overview on migrating to Pylon, see 📄 Migrating to Pylon
First off, ask the Pylon team if your support system you're using has a special migration process. For example, you can cutover Zendesk seamlessly and continue ongoing threads in Pylon.
Decision: What kind of email migration do you want?
You have 4 options with various tradeoffs. Generally speaking small teams should do Type 1, mid-size Type 2, and large teams Type 3. Type 4 is generally recommended for small to mid-sized teams.
Type 1: Forward to Both
Forward email to both Pylon and the old system until your team is ready. Recommended if you have low ticket volume and/or small (< 5 person) teams.
Pros
Fast (few days). You hook up email, vibe it out whether you like it, and shut the old system down after a few days.
Easiest upfront and least amount of work. You're essentially trading off ease of getting started with a data mess afterward.
Run both systems in parallel. Note though, If you're looking to test in parallel, we recommend to use a test email or migrate an unimportant email instead.
Cons
Confusion for your team and customers. We can't pick up replies from your old system so issues in Pylon will be lossy and vice versa. This is fine with a small team or low volume since you can more easily manually keep track of tickets.
Bad data hygiene. Upon data migration, emails created in the overlap will be duplicated.
Dropped tickets after switching. When your team moves over, ongoing old system tickets will be dropped. [Optional] You will need to blast customers to re-open tickets.
Instructions for Type 1: Forward to Both
Setup email forwarding:📄 How do I setup my support email?
Tell your team to get a feel for emails in Pylon.
After a few days, if everyone feels happy about Pylon, disconnect email from your old system.
[Optional] Blast the open old system tickets telling them to open a new ticket if they want continue an issue.
Type 2: One-Day Cutover
Setup email forwarding on Pylon and disconnect email from your old system on the same day. Immediately reply to all open old system tickets that to continue an issue they will need to open a new ticket. Recommended if you have short time to resolutions, you want minimal disruption to your team, and/or mid-size team.
Pros
Fastest (1 day). Everything can happen on that one cutover day. No need to remember to do lingering tasks.
Minimal disruption to your team. Your team only lives out of one system at a time. You're essentially trading off disruption of your team vs disruption of your customer.
If you use Customer Portal, only a small gap in customer ticket visibility. We can kick off the data migration right after the cutover.
Cons
Disruption to your customer. Any customers with open tickets will need to re-submit a ticket to your support email so it is tracked in Pylon. This is fine if you have very quick resolution times.
Instructions for Type 2: One-Day Cutover
Setup email forwarding:📄 How do I setup my support email?
Send a bulk reply to all open tickets telling customers you're switching to a new support system and to re-submit a new ticket to continue to receive support from your team.
Setup a trigger in your old system that fires when a customer replies to send an auto-reply that you've swapped support systems and they need to re-submit a new ticket.
Disconnect email from the old system.
Type 3: Duration Cutover
Setup email forwarding on Pylon and and disconnect email from your old system on the same day. Allow for 1 week to 1 month for ongoing old system tickets to close before telling customers to move. Recommend if you have long time to resolutions, you want minimal disruption to your customers, and/or large teams.
Note: not all support systems can handle a Type 3: Duration Cutover depending on how the old system implements email.
Pros
Minimal disruption to your customers. For most of your customers, the cutover will be seamless and they won't experience any change.
Cons
Disruption to your team. Your team will need to juggle two support systems.
Slowest (1 week - 1 month). This can delay shutting off your old system for an extra month.
If you use Customer Portal, there's a large gap in customer ticket visibility for the duration of the cutover.
Instructions for Type 3: Duration Cutover
Setup email forwarding:📄 How do I setup my support email?
Depending on whether your old support system supports continuing email threads after disconnection, you can disconnect email from your old system. (Supported: Zendesk, Unsupported: Intercom)
Your team will continue to finish ongoing tickets in your old system while answering the new tickets in Pylon. If agents are interchangeable on the same ticket, you can make this easier for your team by moving people over one by one.
After a week to a month if there are still lingering tickets:
Send a bulk reply to all open tickets telling customers you're switching to a new support system and to re-submit a new ticket to continue to receive support from your team.
Setup a trigger in your old system that fires when a customer replies to send an auto-reply that you've swapped support systems and they need to re-submit a new ticket.
Type 4: Seamless Cutover
This cutover is only possible with certain support systems (Zendesk, Front, and manually with Intercom). The idea is to "email" the tickets into Pylon.
On cutover day, we need access to your support system as well as Google admin if you haven't enabled email forwarding yet. We walk you through a workflow that sends a message to your customers and creates that ticket automatically in Pylon. You would then be able to answer to that request from within Pylon and the whole thread would be visible to the customer.
PROs:
Cleanest way to cutover. There is limited time between the cutover and the data migration
You can answer all your open tickets in Pylon - You will also the whole thread in Pylon.
CONs
You need to email your customer once. You can define the copy on this message.
Instructions for Type 4: Seamless Cutover
Close as many tickets in your legacy system as possible.
Follow the instructions from the migrations team provided during the call.
Make sure you don't email very old open tickets or sensitive customers
Adjust the copy of the message to your liking.
