Upgrade to 5.1.13 from quite an old version?

Re: https://www.litespeedtech.com/support/forum/threads/lsws-5-1-13-released.14663/#post-96407

What are the "focused DDoS attacks detected just a few hours ago" ?

I have run a server with an older PHP version and older Litespeed (very stable), so now if I update it to 5.1.13 should all go fine without need to update php or something else, will there be any implications?

LS Enterprise v4.2.21
PHP 5.6.1 (litespeed) (built: Oct 5 2014 17:48:51)

should be no problem on php configuration. since you have a very old version,
To be safe, may try
/usr/local/lsws/admin/misc/lsup.sh -f -v 5.0.19
then
/usr/local/lsws/admin/misc/lsup.sh -f -v 5.1.13

Thanks,
Can I revert to the old version (5.x -> 4.x) at all after getting to 5.x, in case there are problems ?

Yes, you can revert, no problem.

All seems to work fine, but there is this in the log:
NOTICE #_AdminVHost:lsapi] [STDERR] PHP Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /opt/lsws/admin/html.5.1.13/service/serviceMgr.php on line 23

Is there any probelm to login to your LSWS Web Admin? If not, may not need to worry. Admin used to use different php binary to serve admin pages. If yes, we may need detailed steps to reproduce it.

What exactly was a target and how did you fix it? We are on 5.1.13 now and looks like our web servers are still affected.
