Dup\u0103 ce compania Zextras a publicat<\/a><\/noindex> a lansat propriile versiuni ale Zimbra Collaboration Open-Source Edition 9, mul\u021bi administratori au decis s\u0103 \u00ee\u0219i actualizeze serverele de email la noua versiune \u0219i s-au adresat asisten\u021bei tehnice Zextras cu \u00eentrebarea cum pot face acest lucru f\u0103r\u0103 a periclita func\u021bionarea unuia dintre sistemele esen\u021biale ale companiei.<\/p>\n

Tranzi\u021bia la Zimbra OSE 9 de la Zextras se poate face \u00een dou\u0103 moduri. Prima \u0219i cea mai simpl\u0103 \u0219i rapid\u0103 op\u021biune este actualizarea Zimbra 8.8.15 OSE pe server la noua versiune. Exist\u0103 dou\u0103 dezavantaje pentru aceast\u0103 abordare. Primul - va fi necesar un timp tehnic considerabil pentru a efectua actualizarea, iar al doilea - \u00een cazul \u00een care ceva nu merge conform planului, ri\u0219ti s\u0103 r\u0103m\u00e2i f\u0103r\u0103 un sistem func\u021bional \u0219i po\u021bi pierde mult timp pentru a-l face din nou s\u0103 func\u021bioneze. A doua metod\u0103 de tranzi\u021bie la Zimbra OSE 9 este migrarea de la un server bazat pe Zimbra OSE 8.8.15 la un server cu Zimbra OSE 9. Aceast\u0103 abordare este pu\u021bin mai complex\u0103, \u00eens\u0103 nu necesit\u0103 o \u00eentrerupere tehnic\u0103 lung\u0103, iar \u00een caz de probleme pe un server, vei avea \u00eentotdeauna un alt server cu Zimbra OSE complet func\u021bional la \u00eendem\u00e2n\u0103.<\/p>\n

\"Migrarea<\/a><\/noindex><\/p>\n

Pentru a efectua actualizarea, este necesar s\u0103 desc\u0103rca\u021bi distribu\u021bia Zimbra 9 OSE de pe site-ul Zextras \u0219i s\u0103 rula\u021bi instalatorul, care va detecta automat Zimbra OSE 8.8.15 instalat\u0103 \u0219i va oferi op\u021biunea de a actualiza serverul de email la noua versiune. Procesul actualiz\u0103rii este similar cu procesul de instalare a Zimbra OSE 9, care este detaliat \u00een articolul nostru anterior<\/a><\/noindex>.<\/p>\n

Procesul de migra\u021bie \u00eel vom analiza pe exemplul domeniului company.ro. Zimbra OSE 8.8.15 func\u021bioneaz\u0103 pe nodul mail.company.ro, iar Zimbra OSE 9 va fi instalat\u0103 pe nodul zimbra9.company.ro. \u00cen acest context, \u00eenregistrarea MX din DNS indic\u0103 exact nodul mail.company.ro. Sarcina noastr\u0103 va fi s\u0103 transfer\u0103m conturile angaja\u021bilor companiei din sistemul de email de pe nodul mail.company.ro \u00een sistemul dezvoltat pe nodul zimbra9.company.ro.<\/p>\n

\"Migrarea
\n
\nPrimul pas \u00een realizarea acestuia va fi crearea unei copii de rezerv\u0103 pe un server \u0219i desf\u0103\u0219urarea acesteia pe altul. Aceast\u0103 sarcin\u0103 se realizeaz\u0103 prin intermediul extensiei Zextras Backup, care face parte din Zextras Suite Pro. V\u0103 inform\u0103m c\u0103, pentru a transfera cu succes copia de rezerv\u0103, pe ambele servere trebuie s\u0103 fie instalat\u0103 aceea\u0219i versiune a Zextras Suite Pro. De asemenea, re\u021bine\u021bi c\u0103 versiunea minim\u0103 compatibil\u0103 cu Zimbra OSE 9 este Zextras Suite Pro 3.1, a\u0219a c\u0103 nu \u00eencerca\u021bi s\u0103 efectua\u021bi transferul datelor cu o versiune inferioar\u0103 celei specificate.<\/p>\n

\"Migrarea
\n
\nPentru realizarea migra\u021biei, se recomand\u0103 utilizarea unui hard disk extern sau a unui dispozitiv de stocare \u00een re\u021bea montat \u00een folderul \/opt\/zimbra\/backup\/zextras\/, \u00een care, \u00een mod implicit, se salveaz\u0103 copia de rezerv\u0103 a serverului de po\u0219t\u0103. Acest lucru se realizeaz\u0103 pentru a evita ca crearea copiilor de rezerv\u0103 s\u0103 genereze o sarcin\u0103 suplimentar\u0103 asupra sistemului \u00een func\u021biune.<\/p>\n

\"Migrarea
\n
\nVom \u00eencepemigrarea prin dezactivarea pe ambele servere a func\u021biei de scanare \u00een timp real utiliz\u00e2nd comanda zxsuite backup setProperty ZxBackup_RealTimeScanner false<\/b>. Apoi, pe serverul surs\u0103, vom lansa SmartScan folosind comanda zxsuite backup doSmartScan<\/b>. Datorit\u0103 acestui lucru, toate datele noastre vor fi exportate \u00een folderul \/opt\/zimbra\/backup\/zextras\/, adic\u0103 vor ajunge pe un mediu extern. Dup\u0103 finalizarea opera\u021biei, monta\u021bi suportul pe serverul \u021bint\u0103. De asemenea, dac\u0103 viteza re\u021belei interne permite, se poate folosi utilitarul rsync pentru transferul copiilor de rezerv\u0103.<\/p>\n

Dup\u0103 aceasta, se poate \u00eencepe desf\u0103\u0219urarea copiilor de rezerv\u0103 pe infrastructura \u021bint\u0103. Aceasta se realizeaz\u0103 prin comanda zxsuite backup doExternalRestore \/opt\/zimbra\/backup\/zextras\/<\/b>. La finalizarea desf\u0103\u0219ur\u0103rii, ve\u021bi ob\u021bine o copie func\u021bional\u0103 a vechiului server, care poate fi pus\u0103 \u00een func\u021biune. Pentru aceasta, trebuie imediat s\u0103 face\u021bi modific\u0103ri \u00een \u00eenregistrarea MX a serverului DNS \u0219i s\u0103 redirec\u021biona\u021bi fluxul de mesaje c\u0103tre infrastrucutura \u021bint\u0103. \u00cen plus, este necesar s\u0103 aduce\u021bi modific\u0103ri \u00een numele gazdelor \u0219i \u00een \u00eenregistrarea DNS a nodului zimbra9.company.ru, astfel \u00eenc\u00e2t utilizatorii, c\u00e2nd acceseaz\u0103 clientul web, s\u0103 ajung\u0103 exact la Zimbra OSE 9.\u00a0<\/p>\n

\"Migrarea
\n
\nCu toate acestea, munca nu este \u00eenc\u0103 finalizat\u0103. Problema este c\u0103 mesajele primite dup\u0103 \u00eencheierea backup-ului \u0219i p\u00e2n\u0103 la comutarea fluxului de mesaje pe noul server sunt \u00een continuare stocate \u00een Zimbra OSE 8.8.15, a\u0219a c\u0103 imediat ce mesajele nu mai sosesc pe serverul cu Zimbra OSE 8.8.15, va fi necesar s\u0103 se efectueze din nou un backup. Datorit\u0103 scan\u0103rii inteligente, doar datele absente \u00een backup-ul anterior vor fi incluse. Prin urmare, procesul de tranzi\u021bie a datelor recente nu va dura mult timp.\u00a0<\/p>\n

\"Migrarea
\n
\nAcela\u0219i tip de opera\u021biuni poate fi efectuat \u0219i din consola grafic\u0103 a administratorului. Capturile de ecran prezentate \u00een articol arat\u0103 pas cu pas procesul de creare \u0219i importare a unui backup.\u00a0<\/p>\n

O consecin\u021b\u0103 evident\u0103 a acestei abord\u0103ri de actualizare a serverului este c\u0103 utilizatorii Zimbra nu vor avea acces timp de c\u00e2teva momente la o parte a mesajelor primite \u0219i trimise, dar vor putea continua s\u0103 primeasc\u0103 \u0219i s\u0103 trimit\u0103 mailuri f\u0103r\u0103 probleme. \u00cen plus, \u00een timpul restabilirii efective a con\u021binutului c\u0103su\u021bei po\u0219tale, este posibil s\u0103 existe pierderi de performan\u021b\u0103 \u0219i reac\u021bie a serverului, \u00eens\u0103 toate aceste nepl\u0103ceri sunt mult mai acceptabile dec\u00e2t o \u00eentrerupere tehnic\u0103 prelungit\u0103 \u0219i inaccesibilitatea temporar\u0103 a serviciului.<\/p>\n
