Hello,
I have the cPanel (with cloudlinux) version of LTS 62.0.42 that the support ends in 2 days (31 March 2018)....

I have some questions before I upgrade to the latest stable v.68.

1st - If I go and make the upgrade after the period of end for example at 2 April my clients would have any impact because the LTS support would be no longer supported?

2nd - If I make the update I must expect any kind of problems to dovecot, imap services? I read that after upgrade from LTS 62 some users couldn't authenticate with older email clients like outlook...

For example: SMTP error TLS Changes TLS v.68

I make those questions because in that server I have a lot of clients that use their emails and the mail clients that they use are old enough for example outlook 2002, 2003... (they can't use something newer) and I wonder if this new release will conflict with them (imap, pop3, SMTP authentication)....

Any advice is highly appreciated!

You won't notice an immediate impact, but at that point the version is unsupported and no longer receives updates. It's generally advised to update to a supported version before the current version you are using reaches EOL status.

2nd - If I make the update I must expect any kind of problems to dovecot, imap services? I read that after upgrade from LTS 62 some users couldn't authenticate with older email clients like outlook...
The TLS changes are only applied to new installations of cPanel & WHM as opposed to upgrades. However, we do offer workarounds to restore the previous TLS configuration for Exim should you notice any issues:

Thank you.

Hello Michael,

Thank you for the answers!

Just now I read (is that true?) that the LTS v. 62 extended to June 2018. LTS v62 June 2018
So with that option I hold the server until new LTS v70 come out.

One last question.

It's possible to go straight forward for an update to LTS v70 or I must first "pass" inside v64, v66, v68?

Thank you!

You can update from cPanel & WHM version 62 directly to cPanel & WHM version 70.

Thank you.
