All the basic stuff is installed (Linux, Apache, mysql, php, acp, memcache, phpmyadmin). Next steps are
o- change DNS TTL to 5min
o- move all the files.
o- configure apache
o- migrate the database
o- change the DNS A records
If something goes wrong I can switch the DNS back.
o- logrotation, firewalls and other system stuff
Forgot about mail. Configured!
Now - rsync...
Soooo..... The site is running in a new datacenter, on a new server, on a new OS and with a new structure. I haven't noticed any big visible errors so far. But a lot of optimization work still need to be done.
And new forum software has been released.
Site seems to be zipping along....
nice work!
As you said: fingers crossed.
The biggest part has been done in 24 hours. (Yeah, been busy this weekend 😉
On the other hand, it's so much fun to see how the loading time changes when you adjust here and tweak there!
But some no less important bits and pieces are still waiting in the queue.
Ah... php5_curl and libcurl were missing. Should not be visible to general users. Probably some links in the blog were marked as not active.
Well done 😊)
It seems as if the pages are loading faster than ever before....

This is interesting. What is the RTT from your place to 173.255.228.48 (new) and 216.67.248.129 (old)?
In my case:
new -- round-trip (ms) min/avg/max/stddev = 96.920/98.660/100.988/1.575
old -- round-trip (ms) min/avg/max/stddev = 95.130/96.519/97.668/0.732
From gtmetrics (I use to test the load speed from)
new -- rtt min/avg/max/mdev = 77.028/77.253/77.454/0.321 ms
old -- rtt min/avg/max/mdev = 81.314/83.559/93.021/2.228 ms
The old server was farther than the new one, but the old one showed the lowest load time. However, it was very unstable hence timeouts, outages and overloads.
The only reason I see is the used disk array:
old - RAID 6 - 4x reads (4 times faster, than from a single disk), 1x write
new - RAID 1 - 2x reads, 1x write
Memory is the same (1GB). The rest:
New - 4 cores (4522.00 BogoMIPS 2261.000 MHz)
Old - 2 cores (4701.29 BogoMIPS Xeon E5620 @ 2.40GHz)
New - no management software, unless you install it
Old - cPanel
Not sure if this is related:
New - Ubuntu 11.10
Old - CentOS 5
New - Linux host with Xen
Old - Windows 2003 host with something virtualizing
The old system should (and did) work faster, what was confirmed by tests. But too many VPSes per node and cPanel management software kill the advantage.
Okay ... Here are the results of my ping 😁
