As part of our ongoing programme of service enhancements, we will be performing upgrade work on our Zimbra servers during the month of January.
This work will be undertaken outside of normal working hours (in the evening) and will involve a period of downtime for each server.
We will endeavour to minimise any disruption to service and any inbound email received whilst each server is offline will be queued until the relevant server is live again.
The dates will be as follows – we will be sending reminders beforehand.
Wednesday 17th Jan: Zimbra004 – upgrade to Zimbra 8.7
Wednesday 31st Jan: Zimbra003 – upgrade to Zimbra 8.7
Wednesday 7th Feb: Zimbra002 – upgrade to Zimbra 8.7
Whilst Zimbra 8.8 has just been released, we want to monitor it over the coming months to ensure stability. Once satisfied that it will be reliable we will upgrade to that version.We haven’t forgotten Zimbra001 and will contact customers on this server about moving users in the New Year.
